How to use Stun in a run

Stun is most valuable when it interrupts an opening threat or buys enough time for a first cast, not merely when it adds raw duration.

1. Check the trigger condition.Range, Crit, cast, target, Rush, Stall, and quest requirements decide whether the effect appears at all.
2. Check the first application.Timing can matter more than the final stack count, especially against an opening threat.
3. Separate trigger from amplifier.Confirm the team can create the effect before buying equipment that only improves it.
