Dead Cells

When you reach the areas to spend your cells and select mutations, you want to select a very specific mutation - Ygdar Orus Li Ox (YOLO). This will revive you with some health when you eventually die.

You will unlock the achievement when the mutation activates upon death. Note for actually using this: this does not restore your health potions. Any that you used prior to death will remain used after this mutation activates.
