Enigma

Enigma is an artifact that can be unlocked in the Sunken Tomb level. It can be found in the bottom right of the level. You have to fall to what appears to be the bottom of the world but if you hold right you will bounce up as if off a booster. When this artifact is active, random number generation will still generate use items, but they will turn into Small Enigmas; Small Enigmas are passive items that reduce item cooldown time by 5%.

Only a few use items can be acquired with this artifact active, and  with small enigmas can be very powerful :


 * the Nematocyst Nozzle (how?)
 * Disposable Missile Launcher from the Armory of Risk of Rain (Level)
