Portal

Portal is a mechanic unlocked after completing The Dimension of Anger. Along with Portal, the player also unlocks the ability to assign Perks using the now obtainable Helium. The player gains 45 Helium for this action.

Well, you did it. You followed your instincts through this strange world, made your way through the Dimension of Anger, and obtained this portal. But why? Maybe there will be answers through this portal... Your scientists tell you they can overclock it to bring more memories and items back, but they'll need helium to cool it.

The Portal can be accessed using the blue button under the Maps button, left of the world map.

By using the Portal, the player can soft reset their game, deleting all of their progress other than Helium, Bones, Imp-orts, equipped and carried Heirlooms and Perks. By doing this action, the player can assign Helium from their current run into leveling up Perks. The player also loses access to the Portal after using it, and is required to complete The Dimension of Anger again in order to gain access back to it. However, only access to the Portal is temporarily lost - Helium and Perks are never lost.

Through the Portal menu the player can start a new challenge.

The player can increase the amount of small bonuses they start with each time after using the portal by completing the Scientist challenges. These challenges are unlocked in tiers, where higher tiers of this challenge award even more bonuses. Once a new tier of Scientist is unlocked, previous tiers can't be accessed.

Respec

After first unlocking the Portal, the button View Perks on the bottom bar unlocks. Through that button, the player can see their perks as well as respec them. Respecializing perks allows you to remove levels from perks and convert them back into spendable Helium, which can be used to level other perks. There is no Helium loss by respeccing perks - you get a 100% return on each removed level.

After the Respec button is pressed, a new button called "Remove" is added to the amount selector. You can toggle this button to take off levels from specific perks and potentially assign them elsewhere. This is useful if you make a mistake in your perk distribution.

It is possible to respec only once per run, with no penalties whatsoever. To get another respec after using one, the player has to use the Portal to soft reset their game, or purchase "Portal" from the Bone Trader.

If you have the perk Carpentry and attempt to respec without putting as many or more points back into it, the game will not allow you to respec if your new amount of maximum Trimps falls into one of these criteria:

• is less than

[Fighting group size] * 2.4

• is less than

[Number of Trimps employed] * 2

If you want to respec into a lesser amount of Carpentry, consider firing some workers first. Farmers/Lumberjacks/Miners are the best candidates to lose their jobs, because they are the cheapest to move around due to their low, unchanging hiring cost.

Similar criteria are in place for the Coordinated perk where the player can't respec into an amount of Coordinated so low that the fighting group becomes too large for the amount of max Trimps owned.

It is also possible to respec directly from the Portal screen which will skip the above requirements.

Portal screen color

The last tier of Scientist challenge completed will change the name and color of the portal screen, like so:

Scientist completed	Screen title	Screen color
None	Time Portal	#008000
Scientist I	Time Portal Mk. II	#00b386
Scientist II	Time Portal Mk. III	#3db0f8
Scientist III	Time Portal Mk. IV	#2a6a93

The colors are represented as color hex values.

Additionally, some backgrounds are a bit more creative, and use more complex CSS styling properties:

Scientist completed	Screen title	CSS background style
Scientist IV	Time Portal Mk. V	repeating-radial-gradient(#01785a 10%, #256e9b 10%, #17394f 10%, #11222e 20%);
Scientist V	Time Portal Mk. VI	transparent radial-gradient(rgba(0, 0, 128, 0.7), rgba(48, 0, 97, 0.7), rgba(0, 0, 90, 0.7))

Trivia

• Before patch 3.21 it was impossible to use a respec from the Portal screen.
