Triggering enrage without a plan (if the paired unit dies, the survivor may double-spin).

Positioning rules

Don’t cluster within 1 tile of the boss if spin is likely.
If you must hit, do it with fewer, higher-value actions rather than many small pokes.
Keep a cleanse/sustain plan for Poison if the reaction shot is frequent.
