Heirlooms

Heirlooms are special items that can be brought through Portals and grant bonuses (multipliers and new abilities) through a set of upgradeable modifiers.

There are three types of Heirlooms: Shield, Staff and Core, each with a different set of modifiers they can contain.

Each Heirloom is assigned a rarity which is permanent and cannot be changed. Heirlooms of a higher rarity may have more modifier slots, provide stronger bonuses, and grant access to more powerful modifiers.

Shield and Staff heirlooms drop whenever a Void map is completed. Each Void map gives exactly one Heirloom. Since Void maps are only available after the player has used the Portal 5 times, the same applies to these Heirlooms.

Core heirlooms are available when the player completes a Spire after their first time.

The UI

The Heirlooms menu can be accessed by clicking the button located below the Maps button.

Resource Summary

Along the top is a bar which indicates the total Nullifium and Spirestones available to spend on Heirlooms. Nullifium is not consumed by spending it on Heirlooms, but Spirestones are.

Equipped Inventory

The equipped Heirlooms inventory can be found in the top left corner. Heirlooms can be equipped by clicking on them from either the Carried or the Temporary inventory and then pressing Equip or Swap, depending on whether there's already an Heirloom equipped in the corresponding slot. Heirlooms can be freely moved between inventories at will, at any time, with no penalties.

The player can only equip one Heirloom of each type, so up to three Heirlooms can be active at once. An Heirloom's modifiers will be applied as soon as it's equipped.

Equipped Heirlooms carry on through Portals.

Carry Inventory

Under the equipped inventory, there's a menu where the player can store Heirlooms. Any Heirlooms stored in this area will carry on through Portals, and will not be reset. This can be used as means of storing certain Heirlooms the player doesn't want to lose.

Heirlooms can be put here by clicking on them, then pressing Carry.

This inventory starts with just one available slot. By pressing the "add slot" button the player can purchase more slots permanently at the cost of some Nullifium. The player can purchase a maximum of 10 extra slots. The cost to purchase the second slot is 40, then 80, 120, 200, 600, 1200, 3200, 8000, 20000, 60000. Each of these costs represents each Heirloom rarity's worth times eight. The player can also earn up to 3 more free slots (grand total: 14 slots) by clearing Spires I to III for the first time. Note that these are permanent losses in Nullifium, and affect the total Nullifium available to invest in upgrading Heirlooms.

Temporary Inventory

In the bottom left, there's a menu for all left-over Heirlooms. This is where newly dropped Heirlooms from completed Void maps and Spires will appear.

Heirlooms stored in this inventory will be lost upon using the Portal, and the player will receive their value's worth in Nullifium (Shield and Staff) or Spirestones (Core). Heirlooms stored here can also be manually recycled at any point by clicking on them, then pressing Recycle - this action will also award the Heirloom's value worth in Nullifium/Spirestones. All Heirlooms stored here can also be recycled at once by clicking the Recycle All button.

Upgrade menu

To the right, there's a menu which will display the properties of the currently selected Heirloom.

Clicking the Heirloom's icon or name will allow the player to change it. By default, the names are a combination of rarity + type, for example "Common Shield". This action doesn't cost anything and has no penalty attached, meaning the icons and names can be changed at will.

Underneath the Heirloom's name is a counter indicating how many resources (Nullifium or Spirestones) have been spent on that Heirloom, and, for Shields and Staffs, how much of that Heirloom's available Nullifium remains to be spent on it.

Clicking a modifier will cause a window to appear below the heirloom details. On the left side of this window, the player can replace the selected modifier with the one selected through the drop-down list at the cost of the displayed amount of Nullifium/Spirestones. On the right side, the selected modifier can be upgraded to a higher multiplier, also at the cost of some Nullifium/Spirestones.

New as of 5.0.0: Nullifium is not permanently spent when upgrading an Heirloom. Each Heirloom may be upgraded up to a percentage of your total Nullifium. See the Upgrading Section.

Heirloom Rarities, Value, and Modifiers

When the game spawns an heirloom, it is assigned a type and a rarity. This rarity determines the number of modifier slots, the resource value, and an upgrade growth factor for the Heirloom. The modifiers that are available depend on the type of Heirloom and its rarity. Each rarity also corresponds to a maximum cap on select modifiers. These are summarized in the table below.

Heirloom Properties according to Rarity

Rarity	Slots	Nullifium / Spirestone Cost	Growth Factor	Modifier Caps
				Condensor Effect	Crit Chance	Void Map Drop Chance	Plague­bringer	Prismatic
Common	1	5 Nu / 20 Ss	1.5		30%	50%
Uncommon	2	10 Nu / 200 Ss	1.5	10%	30%	50%
Rare	3	15 Nu / 2000 Ss	1.25	10%	30%	50%
Epic	3	25 Nu / 20K Ss	1.19	15%	30%	50%
Legendary	3	75 Nu / 200K Ss	1.15	25%	30%	50%
Magnificent	4	150 Nu / 2M Ss	1.12	35%	30%	50%
Ethereal	4	400 Nu / 20M Ss	1.1	50%	30%	50%
Magmatic	5	1000 Nu	1.06		30%	50%
Plagued	5	2500 Nu	1.04		100%	80%	75%
Radiating	6	7500 Nu	1.03		125%	99%	100%	250%

Table notes:

Modifiers are assigned randomly when an Heirloom is created. There is a chance (1/11 chance for a Shield, 1/12 chance for a Staff) for the last modifier slot to be left empty. However, this does not apply to Common and Uncommon Heirlooms, or Cores of any rarity.

Each modifier will be given a random starting value within an allowable range for the specific modifier at that rarity.

Modifiers that appear on an Heirloom will initially be sorted alphabetically. Replacing modifiers will not sort them, meaning that by doing so different modifiers can be made to appear in different places.

Upgrading and Recycling Heirlooms

A currency called Nullifium is used to upgrade Shields and Staffs, while Spirestones are used to upgrade Cores.

As of v5.0, Nullifium is not permanently spent to upgrade Heirlooms. Instead, 50% of total Nullifium earned (minus that spent on increasing Carry capacity) can be used to upgrade each Shield and Staff Heirlooms separately. For example, having 1000 total Nullifium means 500 Nullifium can be spent upgrading every available Shield or Staff.

Recycled Heirlooms behave differently depending on their type. Recycled Shields and Staffs will have their own worth added to the total Nullifium pool, but will not re-contribute the Nullifium invested in them (because it is already available for other Heirlooms to use). Recycled Cores will contribute their Spirestone value as well as the value of Spirestones invested in them. Note that exceeding the cost of the next floor of the Player's Spire will cause it to be automatically purchased. This means it may not be possible to completely recoup the Spirestones invested in a Core when doing so would trigger the Spire floor purchase.

With the Heirnuum Masteries, the proportion of total Nullifium that can be spent on Staffs and Shields are increased.

The cost to upgrade a single modifier by one step is equal to that Heirloom's worth (1x).

Heirlooms can be upgraded past their maximum value, indefinitely, with the exception of Condensor Effect (for Cores), and Crit Chance, Void Map Drop Chance, Plaguebringer, and Prismatic (for Shields). These have hard caps determined by their rarity, indicated in the "Modifier Caps" columns of the above table.

If the current multiplier of a modifier has been upgraded once past its maximum, each successive upgrade will have an exponentially increasing cost based on its rarity, indicated in the "Growth Factor" column of the table above.

For example, buying the last step for a Common Shield will cost 5 Nullifium; after that, upgrading it further will cost 7, 11, 16 Nullifium etc.

The final cost of upgrades past maximum is rounded down at the very end of calculation.

The cost of adding a modifier to an empty slot is equal to two times of that Heirloom's worth (2x).

The cost of replacing a modifier with a different one is equal to six times of that Heirloom's worth (6x).

Shield and Staff Heirlooms

By completing a Void Map, either a Shield or a Staff will drop, with an equal chance of each.

Staffs provide boosts to resource gathering and looting, while Shields provide boosts to combat, Void Map drops and other miscellaneous bonuses.

Rarity chances

The chances for each rarity depend on the current zone a Void map was completed at. Numbers in parentheses and italics indicate the new bonus drop rate from Fluffy.

Plagued Heirlooms

A new type of Heirloom called Plagued Heirlooms can be found only at Zones 500+. This is the first type of Heirloom that has an animation (rotating).

Every Plagued Heirloom will spawn with one Empty slot, with a chance (1/13 chance for a Staff, 1/12 chance for a Shield) for another Empty slot.

Unlike lower rarity Heirlooms, modifiers on these Heirlooms cannot be replaced. (The player may still add modifiers to empty slots.) Plagued Shields are also different from the lower rarities in that they have increased caps for Crit Chance (100%) and Void Map Drop Chance (80%).

There is one new modifier (Plaguebringer) exclusive to Plagued Shields and one new modifier (Pet EXP, affecting Fluffy/Scruffy) exclusive to Plagued Staffs.

Plaguebringer allows a percentage of all non-lethal damage and Nature stacks you afflict on your current enemy to be copied onto the next enemy. Plaguebringer damage cannot bring an enemy below 5% health, but nature stacks will continue to accumulate. Note that Plaguebringer has no effect when enemies are overkilled, and requires enemies to be alive to have any effect.

Radiating Heirlooms

Once the player is in the Radon Universe, all Heirlooms earned will be greatly weaker in this new world (10% effect). The exception are the modifiers Crit Chance, Void Map Drop Chance, Plaguebringer ad Pet EXP, which can be brought back to normal once the player levels Scruffy to Level 2. To compensate for this fact, a new type of Heirloom will drop, known as Radiating Heirlooms. They have a pulsing animation, signifying radiation of some sort.

Just like Plagued Heirlooms, these will spawn with one Empty slot, with a chance (1/13 chance for Staff; 1/11 chance for Shield) of another Empty slot. Likewise, existing modifiers cannot be replaced. Adding a new modifier to an Empty slot will work as usual. The skill caps are further increased from Plagued Heirlooms, with Radiating Heirlooms capping out Crit Chance of 125%, Void Map Drop Chance at 99%, Plaguebringer at 100% and Prismatic Shield at 250%.

The following modifiers are present only on Radiating Heirlooms (percentages are for U1):

• Plaguebringer (Shield): Min 15%, max 30% with a step of 0.5%
• Prismatic (Shield): ADDS this amount on to your total Prismatic Shield. This modifier can only function in the Radon Universe. Min 10%, max 50% with a step of 1%
• Gamma Burst (Shield): Every time your Trimps attack, adds 1 stack of Charging. When Charging reaches 5 stacks, your Trimps will release a burst of energy, dealing a certain percentage of their attack damage. Stacks reset after releasing a Burst or when your Trimps die. Min 1000%, max 2000% with a step of 100%.
• Pet EXP (Staff): Min 50%, max 100% with a step of 1%

The following modifiers are NOT present on Radiating Heirlooms (due to Block being absent in the Radon Universe):

• Storage Size
• Trainer Efficiency
• Trimp Block

Spire Core Heirlooms

By completing Spires in the world, a Heirloom Core is guaranteed to drop, with the exception of the first Spire clear, where 20 Spirestones are awarded.

Cores are used to provide bonuses to the Traps/Towers in the Player's Spire.

Each Spire will drop a Core of the specified rarity as depicted by the table below:

Spire Cleared	Core Type drop	Spirestone Worth
Spire I	Common	20
Spire II	Uncommon	200
Spire III	Rare	2k
Spire IV	Epic	20k
Spire V	Legendary	200k
Spire VI	Magnificent	2M

Trivia

• In patch 5.0, another brand new rarity of Shield/Staff Heirloom was introduced (Radiating), together with the Radon Universe. All Staffs and Shields are much weaker in this new universe (10% of original effect).
• In patch 4.11, a brand new type of Heirlooms were introduced (Cores). Common and Uncommon Heirlooms can no longer spawn with an Empty slot, and have the same values for modifiers as Rare Heirlooms. Rare Heirlooms now have 3 modifier slots (up from 2). Drop rates for Heirlooms up to zone 300 were improved. In addition, two new rarity breakpoints are introduced at z600 and z700.
• In patch 4.8, a new tier of Heirlooms is introduced (Plagued) which is obtained on Zones 500+. Two new modifiers are exclusive to this type. To accommodate this, the z400+ rarity breakpoint was changed to z400-z499, and a new rarity breakpoint z500+ was added.
• In patch 4.5, the z300+ rarity breakpoint was changed to z300-z399, and a new rarity breakpoint z400+ was added.
• In patch 4.1, the Magmatic rarity was added, and the number of carried slots was increased by 1. Also, prior to 4.1, it was impossible to retrieve any Nullifium spent on an Heirloom. Recycling Heirlooms would not give back any Nullifium spent on upgrades. This works retroactively - any Heirlooms that were found and upgraded prior to 4.1 can now be recycled for full value with all the upgrades.
• In patch 3.3, the z181+ rarity breakpoint was changed to z181-z200, and a new rarity breakpoint z201+ was added.
