Shop decision
When this relic shows up — buy, hold, or skip.
- Best for
- Best for Tank boards that want a class identity piece — take it when you are committing that class, not dabbling.
- Skip when
- Skip when you are not running Tank, or you rarely trigger Poison, or this would be your only piece of that fantasy.
- Shop note
- Unique engine / identity piece. Prefer it when the board already leans this direction. Stack Poison support around it.
