Player's Spire

You've also found a large, pulsing core that seems to be powering the Spire. You try to carefully remove it but instead smash it into 20 still-humming pieces! You give the pieces to your Scientists, who name the magical new material "Spirestones" and use them to begin construction on your own Spire! - Message upon clearing the Spire for the first time

The Player's Spire is a new feature added in 4.10. It allows you, the player to build your own Spire after defeating Druopitee in the Spire at Zone 200. Build up Towers and Traps in order to kill enemies passing through the Spire, make your Spire more threatening by raising Threat and experiment with new strategies in this new tower defense simulation, a "game within a game".

Description and Screen

Once the player defeats Druopitee and clears the Spire for the first time, the Player's Spire is unlocked and is shown to the player. A new tab will also unlock next to the Mastery (and Nature) tab. Clicking this tab, or pressing P on the keyboard will bring the player to the Player's Spire screen.

The Player's Spire screen upon first unlock

On the left is your Spire, where enemies will periodically wander through it harmlessly. This is where you can place Towers and Traps in order to attempt to kill them.

On the right is the screen for Settings and Tower/Trap information, as well as for any upgrades for them.

The player may choose to shrink the screen by clicking on the "Shrink Window" button, which will compress the right of the screen and only display the Spire on the left, as well as a condensed list of Towers/Traps and upgrades (if any).

Spire Layout and Threat

Initially, only the first row of the Spire is unlocked, containing 5 cells for enemies to pass through and to place Towers and Traps. Killing enemies will award a new currency called Runestones, which are needed for more Towers/Traps and their upgrades. In addition, your Spire becomes more threatening to future enemies, causing them to grow stronger and subsequently earn more Runestones from killing them.

The Threat is a measure of how strong your current Spire is, and corresponds directly to the health of enemies that will spawn. Threat increases as enemies are killed and decreases as enemies manage to survive to the end of your Spire and escape.

Up to 20 rows of the Spire (with 100 cells total) can be unlocked. In order to build more floors of your Spire, a new currency called Spirestones is required. Spirestones are obtained from recycling Spire Core Heirlooms, themselves obtained by clearing Spires in the world, with higher Spires rewarding better Heirlooms that are worth more Spirestones. Their rewards are as shown below:

Spire Beaten	Spire Core Rarity	Spirestone Worth
Spire I	Common	20
Spire II	Uncommon	200
Spire III	Rare	2000
Spire IV	Epic	20K
Spire V	Legendary	200K
Spire VI	Magnificent	2M
Spire VII	Ethereal	20M

The requirements for each floor (maximum of 20) are as shown below:

Floor	Spirestone Cost	Threat Level
2	6	200
3	14	300
4	20	400
5	60	500
6	200	600
7	400	700
8	800	800
9	1600	900
10	2500	1000
11	5500	1100

14	55K	1400
15	100K	1500
16	150K	1600
17	200K	1700
18	1M	1800
19	2M	1900
20	4M	2000

Towers/Traps and Upgrades

By placing Towers and Traps, it becomes possible to damage and kill enemies passing through your Spire. There are 7 of them in total: 4 Traps and 3 Towers. They are the Fire Trap, Frost Trap, Poison Trap, Lightning Trap, Strength Tower, Condenser Tower and Knowledge Tower. Their initial cost, scaling and unlock requirements are shown in the table below:

Tower/Trap	Base Cost (Runestones)	Scaling effect	Unlock By
Fire	100	1.5x	Unlocked at start
Frost	100	5x	Unlocked at start
Poison	500	1.75x	Complete Spire II
Lightning	1000	3x	Complete Spire III
Strength	3000	100x	Build the second floor of your Spire
Condenser	6000	100x	Complete Spire II
Knowledge	9000	100x	Complete Spire III

Traps and Towers can be sold for a full refund (100% cost) of the Runestones spent on them. This allows the player to experiment with the layout in order to maximise the damage output.

Fire Trap

This trap deals 50 damage to each enemy stepping on it.  By upgrading this trap, it will be able to deal more damage, and even reward extra Runestones when landing the killing blow on an enemy. Its upgrades are shown in the table below:

Upgrade	Requirements		Effect
	Cost (Runestones)	Highest Zone
II	50K	250	All Fire Traps gain 10x damage.
III	5M	300	All Fire Traps gain 5x damage.
IV	25M	375	Double the damage of all Fire Traps, and all Fire Traps will instantly kill any enemy that has 20% or less health.
V	75M	425	Double the damage of all Fire Traps.
VI	5B	500	Dectuple the damage of all Fire Traps.
VII	500B	590	Dectuple the damage of all Fire Traps once more, and all enemies drop 20% extra Runestones when they die on a Fire Trap.
VIII	100T	650	All Fire Traps gain 100x damage.

Frost Trap

This trap deals 10 damage when stepped on, and causes the target to become Chilled, slowing movement to 50% speed for 3 cells. This speed reduction causes the target to stay on each Trap for twice as long, triggering each Trap twice. Note that Frost Traps are coated with antifreeze, preventing chill effects from working while an enemy is standing on a Frost Trap. Upgrade them to increase damage, Chill duration and other bonuses. Its upgrades are shown in the table below:

Upgrade	Requirements		Effect
	Cost (Runestones)	Highest Zone
II	10K	230	Multiply Frost Trap damage by 5, and increase the duration of Chilled by 1 cell.
III	500K	275	Multiply Frost Trap damage by 10. Chilled enemies now take 25% more damage from Fire Traps.
IV	2.5M	330	Multiply Frost Trap damage by 5. If there is a Poison Trap directly before a Frost Trap, that Poison Trap becomes 4x as effective.
V	100M	430	Multiply Frost Trap damage by 2, and each time an enemy can't move because it is slowed, that enemy becomes worth 2% more Runestones. This effect stacks additively.
VI	50B	530	Multiply Frost Trap damage by 5, and increase the duration of Chilled by 1 cell.

Poison Trap

This trap adds 5 Toxicity when stepped on. Target will take damage equal to its total Toxicity each time it attempts to move. Upgrade them to increase the Toxicity applied, and to harvest Runestones from escaped enemies. Its upgrades are shown in the table below:

Upgrade	Requirements		Effect
	Cost (Runestones)	Highest Zone
II	10M	350	Double the amount of Toxicity added when an enemy steps on any Poison Trap.
III	50M	400	If there is a Poison Trap either directly before or after another Poison Trap, both Traps gain 3x damage. If a Poison Trap has Poison Traps on both sides of itself, it gains 9x damage instead.
IV	750M	450	Double the amount of Toxicity added when an enemy steps on any Poison Trap.
V	100B	550	Double the amount of Toxicity added when an enemy steps on any Poison Trap. In addition, if the enemy has 75% or less health remaining, the final amount of Toxicity added is multiplied by 5.
VI	1T	600	Double the amount of Toxicity added when an enemy steps on any Poison Trap. In addition, if an enemy leaks, gain 10% of its total Toxicity as Runestones.
VII	40T	625	Double the amount of Toxicity added when an enemy steps on any Poison Trap.

Lightning Trap

This trap deals 50 damage when stepped on, and afflicts the target with 1 stack of Shocked. 1 stack of Shocked is consumed each time an enemy steps on a Trap or Tower, causing that Bad Guy to take 2x damage and 2x effect from the Trap or Tower that consumed the stack of Shocked. Shocked can boost the damage but not the effect of other Lightning Traps. Upgrade them to increase Shock stacks and their bonus damage and effect taken from other Traps/Towers. Its upgrades are shown in the table below:

Upgrade	Requirements		Effect
	Cost (Runestones)	Highest Zone
II	500M	440	Lightning Trap gains 10x damage, and Lightning Trap now adds 2 stacks of Shocked.
III	5B	500	Lightning Trap gains 10x damage, and Shocked now causes the target to take 4x damage and Toxicity from Traps. Towers and slows are not boosted by this extra damage.
IV	250B	575	Lightning Trap increases the damage and effect of Fire and Poison Traps in its column by 10%, stacking additively with other Lightning Traps in the column.
V	1T	600	Lightning Trap gains 10x damage, and Lightning Trap now adds 3 stacks of Shocked.
VI	1Qa	675	Lightning Trap gains 10x damage, and Shocked now causes the target to take 8x damage and Toxicity from Traps. Towers and slows are not boosted by this extra damage.

Strength Tower

This Tower (max of 1 per Floor) increases the damage of all Fire Traps on the same Floor by 100%. When stepped on deals damage equal to the cumulative damage of all Fire Traps on its Floor (after Strength Tower Effect). In addition, this Tower increases the attack of your Trimps in Maps and the World by 30% (additive with other Strength Towers). Upgrade them to increase the attack boost to your Trimps. Its upgrades are shown in the table below:

Upgrade	Cost (Runestones)	Effect
II	1M	Each Strength Tower grants an additional 15% attack to your Trimps.
III	10B	Each Strength Tower grants an additional 15% attack to your Trimps.
IV	100T	Each Strength Tower grants an additional 15% attack to your Trimps.
V	1Qi	Each Strength Tower grants an additional 15% attack to your Trimps.

Condenser Tower

This Tower, when stepped on, increases the target's Toxicity by 25% (multiplicative). In addition, each Condenser Tower increases all Helium found by 10% (additive with other Condenser Towers). Upgrade them to increase the Helium bonus. Its upgrades are shown in the table below:

Upgrade	Cost (Runestones)	Effect
II	2M	Each Condenser Tower grants an additional 5% Helium earned from all sources.
III	20B	Each Condenser Tower grants an additional 5% Helium earned from all sources.
IV	200T	Each Condenser Tower grants an additional 5% Helium earned from all sources.
V	2Qi	Each Condenser Tower grants an additional 5% Helium earned from all sources.

Knowledge Tower

This Tower causes Chilled enemies that step on it to become Frozen, slowing the target to 33% speed for 5 cells. In addition, each Knowledge Tower increases Fluffy's Experience gain by 15% (additive with other Knowledge Towers). Note that Knowledge Towers are coated with antifreeze, preventing chill effects from working until the enemy steps off of this Tower. Upgrade them to increase the Fluffy EXP bonus. Its upgrades are shown in the table below:

Upgrade	Cost (Runestones)	Effect
II	3M	Each Knowledge Tower grants an additional 7.5% Fluffy Exp earned from all sources.
III	30B	Each Knowledge Tower grants an additional 7.5% Fluffy Exp earned from all sources.
IV	300T	Each Knowledge Tower grants an additional 7.5% Fluffy Exp earned from all sources.
V	3Qi	Each Knowledge Tower grants an additional 7.5% Fluffy Exp earned from all sources.

Enemies

Periodically, enemies will wander through your Spire. One enemy will enter your Spire every 3 seconds. They are represented by boxes with icons moving through your Spire. Only a certain number of enemies may be in your Spire at any time, as shown below: 

Floors available	Max enemies allowed

Below 20%	#541411	#ec352c

Status effects

Enemies may be affected by several status effects which are inflicted by Traps.

Chilled

Chilled enemies move at half speed, causing them to step on any Trap/Tower twice for the duration of the effect. Enemies' life bars will have a blue section next to their health bar.

Frozen

Frozen enemies move at one-third speed, causing them to step on any Trap/Tower thrice for the duration of the effect. Enemies' life bars will have a purple section next to their health bar.

Shocked

Shocked enemies are more vulnerable to the status effects and damage from any Tower/Trap they step on for the duration of the status effect. Affected enemies' health values/health % values will be written in yellow.

Tutorial

There is a tutorial system for the Player's Spire. At the beginning, only the first row of the Spire is unlocked, with the Fire Trap and Frost Trap available. By completing the quests highlighted in bold, more Traps, Towers and Spire floors will be available.

No.	Message
1	Welcome to your Spire! You've killed Druopitee and stolen some Spirestones: ancient construction materials that duplicate themselves across dimensions, traditionally used to create powerful Spires. Druopitee thought that he was the only one who could build tall buildings, but you're on a mission to prove him wrong! You were able to finish constructing the first Floor of your very own Spire with the Spirestones you found, and you still have a few left over to try to make it even taller. You had your Trimps build a wall around the entire town, making your new Spire the only entrance and exit point. You feel super safe for a few seconds, and your Trimps are super stoked on their new fortress. After those few seconds are up, you see that the Spire is attracting a decent amount of unwanted attention from jealous enemies, who seem to take your Spire as a challenge. Luckily, your Scientists have managed to come up with a few Trap designs that can hopefully stop the flow of enemies into your town. Try placing a Frost Trap in the leftmost cell of your Spire, and a Fire Trap directly to the right of it.
2	Perfect, everything seems to be working just as your Scientists explained. The Frost Trap slows the enemies down, and the Fire Trap finishes them off. Unfortunately, it seems like each enemy you kill in here makes your Spire a more important target, causing stronger and stronger enemies to come through. Fortunately though, your Magical Spire Traps convert Bad Guys into a new type of resource whenever they kill one, which your Scientists call 'Runestones'. Even more fortunately, larger enemies with more Max Health convert into larger amounts of Runestones! As your Spire's Threat increases, so will your Runestones per second, and so will your Spire's defenses (if you're doing your job). You don't have to stay here while Runestones build up, you can go back to leading your Trimps while your Traps do some work. The enchanted Spirestones copy your progress to all possible dimensions, so you won't even lose your Traps if you Portal! Keep an eye on your Runestones, and add more Traps whenever you can. Try to fill this entire Floor with Traps!
3	You're a natural Spiarchitect! Your Scientists have finally finished adding the second Floor of your Spire, and the added height seems to be attracting even more enemies. Cool, more Runestones for you! You're starting to really like the idea of enemies constantly climbing to their demise in the teeth of your Traps. While you're appreciating your deadly handiwork, a small group of Scientists runs up to you and shares some new research. They say that the Runestones can also be used to create mini-towers that broadcast their energy to all Trimps in the World. Wasting no time, they hand you the schematics for the Strength Tower, which increases the effect of all Fire Traps on its Floor, and grants all of your Trimps an attack bonus. Continue placing more Traps and Towers to fill out your Spire, and raise your Threat level to 300.
4	Beautiful. It seems like you're getting the hang of this! You've finished constructing the third Floor of your Spire, but it seems as if you've used up your entire intial supply of Spirestones. You'll need to clear a Spire again to earn more! Note that you'll find considerably more Spirestones from more difficult Spires. Collect 20 Spirestones and raise your Spire's Threat to 400 to build your fourth Floor.
5	It's getting huge! However, the Traps are getting more expensive as you place more and more of them. At this rate you'll never be able to afford enough Strength Towers to make a huge impact on your Trimps. You consult with your Scientists, who tell you that they can create upgrades for your Traps, but that they need to study corpses of high level enemies in order to exploit their weaknesses. Raise your Highest Zone Reached to Z230, and upgrade your Frost Trap.
6	Wow, look at that thing slow! You seem to have a pretty decent understanding of how to manage your Spire, and I believe you can handle it on your own for a while. Continue to raise your HZE to unlock more upgrades, collect Spirestones to add more Floors and enemies, and tweak your Trap layout every once in a while to make sure you're getting as many Runestones as you can, you'll definitely need them later. Your Scientists let you know that they can possibly forge a new Trap and Tower, but they need to study Spirestones from a higher level Spire first. Complete Spire II to unlock Poison Trap and Condenser Tower! Once you have your new Traps, raise your Spire's Threat to 600 and build your sixth Floor. Remember that you have to satisfy both the Threat and Spirestone requirements to add a new Floor!
7	You've got a new Trap and Tower, your Spire is still growing, and your power is growing with it! Your Trimps are slightly annoyed that they have to clean up the occasional Bad Guy that makes it through the Spire and into the town, but they can handle it. They all agree that life in general is just more fun when there's a giant Spire grinding Bad Guys at the entrance to their town. While you're feeling comfortable maintaining your Spire's defenses with the tools you have, you still feel like there's something missing. Your Scientists say that they could perhaps create one more Trap and Tower, but again they'll need to study Spirestones from an even higher Spire. Clear Spire III to unlock the Lightning Trap and Knowledge Tower, then raise your Spire's Threat to 1100 and build your eleventh Floor.
8	And that's about all there is to teach you! The rest of the management of your Spire is left in your more-than-capable hands. Raise your HZE, clear Spires, buy upgrades, build Floors, and come up with the perfect layout for your Spire. I'll hang out and make sure everything's OK until you reach Threat level 1300 and build your thirteenth Floor, and then you'll be on your own.

Strategies and Tips

• Place all of your Poison Traps at the start of your Spire, to allow enemies to take more poison damage as they progress through your Spire.
• Place a Frost Trap, then a Lightning Trap at the end of a row, then a Strength Tower and 4 Fire Traps on the row after it. This causes Shocked enemies to step on the Strength Tower twice, taking a lot of damage.
• Place a Lightning Trap, then your Condenser Towers immediately after your last Poison Trap, alternating with Lightning Towers, to drastically increase Toxicity applied.
• In short, first place a group of poison traps, then a group of condenser towers. The final part is a group of fire traps.
• It might be worth it to sell most of your Towers and Traps for a powerful upgrade.
• You can shift a Tower/Trap and all others after it up/down one cell at a time, by pressing the Shift Up/Shift Down buttons, then the Tower/Trap you want to move.
• Since there is no downside to selling a Trap/Tower, you can tinker with the layout as you please. Experiment to get the best layout!
• With the introduction of Spire Cores, don't forget to equip the most powerful Core you can find (and upgrade) to boost your Towers and Traps.
• The best Cores are those with modifiers that synergize well with each other e.g, Fire Trap Damage and Strength Tower Effect, or Poison Trap Damage and Condensor Effect. Both can be further enhanced with Lightning Trap Damage.

Trivia

• The effects of Chilled and Frozen do not stack. This means that a Frozen enemy stepping on a Frost Trap will be Chilled instead of remaining Frozen.
• Chilled and Frozen last for a certain number of cells, but Shocked only lasts for the number of times an enemy steps on a Tower/Trap, so Shocked lasts a lot shorter than the other two effects.
• The Player's Spire, and all its associated elements persist through Portals.
