Slay the Silent

Apply Deadly Poison, then use Catalyst to double (or triple upgraded) the stacks. Multiple Catalysts chain exponentially.

Noxious Fumes stacks Poison passively each turn, making Catalyst increasingly impactful the longer the fight goes.

Use Nightmare on Catalyst to add 3 copies to your hand. Playing them in sequence multiplies Poison by 2×, 4×, 8× (or higher when upgraded).

Burst causes the next Skill to play twice. When that Skill is Catalyst, the enemy's Poison is doubled twice — effectively quadrupled.
