Genetic Algorithm

DefectSkillRare
Gain 1 Block.
Permanently increase this card's Block by 3.
Exhaust.
  • Start: it starts at 1 Block.
  • Growth: each play gives its current Block, then permanently adds 3 to the card, both the copy in this fight and the copy in your deck, so the growth carries across the run.
  • Example: after five plays it gives 16 Block for 1 Energy.
  • Upgrade: it raises the increase to 4 per play rather than the current Block, so an early upgrade compounds.
  • Once: it Exhausts, so it plays once per combat unless something brings it back.

When to take Genetic Algorithm

Good in Act 1 or not at all, since it needs many combats of plays to become a real wall. Upgrade it at the first Rest Site, since every later play is worth 1 more Block forever.
