|In his laboratory, between each two biomes.|
The Collector is an NPC in Dead Cells. He invites the player to give him cells and blueprints, in return for experimental items and more power. All purchases from the Collector are carried over through each run.
Upgrades[edit | edit source]
There are four types of upgrades: general improvements, mutations, weapons, and skills; the latter three of which will unlock a specific item or mutation, after giving the Collector that item's blueprint. In addition to these gameplay elements, the player can also find blueprints for outfits, which will change his appearance at the Tailor.
Health Flask I must be unlocked before anything else.
