How to use Shields in a run

Shield timing is crucial. A large shield that expires before enemy burst may be weaker than a smaller shield applied at the right moment.

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.
