Shop decision
When this relic shows up — buy, hold, or skip.
- Best for
- Best for runs that trigger Crit often enough to stack value across fights.
- Skip when
- Skip when you rarely trigger Crit, or a cheaper enabler would stabilize the board first.
- Shop note
- Unique late luxury. Prefer it when the board already leans this direction. Stack Crit support around it.
