Shop decision
When this relic shows up — buy, hold, or skip.
- Best for
- Best for Assassin boards that need a fight-to-fight payoff loop built around Crit, Stealth, and Poison.
- Skip when
- Skip when you are not running Assassin, or you rarely trigger Crit, Stealth, and Poison, or this would be your only piece of that fantasy.
- Shop note
- Legendary engine / identity piece. Prefer it when the board already leans this direction. Stack Crit, Stealth, and Poison support around it.
