Complete the bridge and let Lasswell’s barrier event resolve before judging damage against the third, winnable encounter. Restore at the crossing and keep Nichol or another Water user available alongside a healer. Check Paralysis recovery before committing.
Answer the dangerous action
Water feeds fury as well as damage. Combine it with gauge pressure so Stagger settles that fury instead of abandoning the weakness. Blistering Hellfire is the party-wide warning: use an achievable break, or prepare Shell and recovery if the gauge is too large.
After the battle
Treat the Mt. Reizan rematch as a fresh encounter with current levels and resources. Afterward, change to Lightning for Alluvion instead of carrying the Water queue into the next battle.
