Modifications

Modifications are special unlockable elements that modify the game. During a run, these can be added to change aspects of play and change the basic rules of the game. Modifications are unlocked by completing it's challenge within The Laboratory. After completing the challenge during a run, that Modification is activated for the remainder of the run.

## Chaos

* Survivors will be hurt by their own skills and items that create explosions, as well as those from their allies. This is very dangerous for melee enemies.
	+ Bomber is relatively unaffected by this, as he already took damage from his own explosions, and damage reduction still applies with this artifact.
* Auto-target attacks will not lock onto allies, making characters like Astrologian and Huntress less likely to kill a survivor.
* Knight's passive means damaging nearby enemies is less likely to kill them. However, it does mean the Knight can kill himself quite easily if not careful.

## Command

* Command Essence is relative to the rarity of an item, and the selection will be of all items of that rarity.
* Unique items like the Pearl do not drop from Yellow Essence, and can only be achieved from Cleansing.
* 3D Printers will not spawn when Command is active.

## Death

* Dying with a Phoenix Egg or Fluctuating Life Force will return the player back to life and not kill the team.

## Enigma

* If the player loses their Chems in any way, they will not get a new one until they start the next stage.
