Shop decision

When this relic shows up — buy, hold, or skip.

Best for: Best as a power spike on Assassin boards once the core loop is online.
Skip when: Skip when you are not running Assassin, or you rarely trigger Crit and Shard, or you cannot secure kills to pay the on-kill line.
Shop note: Epic mid–late power spike. Prefer it when the board already leans this direction. Stack Crit and Shard support around it.
