Read this encounter
Lopros eats summoned prey to heal and strengthen itself. Azure Snapper calls for Lightning and Land Snapper for Wind; deny the meal, then return Ice pressure to Lopros. Read the meal warning before deciding to tunnel on the boss’s remaining HP.
Answer the dangerous action
Old Town leaves Rain, Fina and Lid available while Lasswell and Nichol stay behind. Put Lightning on an available Vision user and keep Fina’s recovery working. Bubble Breath brings Water pressure, and Paralysis can remove the next healing turn: bring a second actor with a cure.
After the battle
Complete Luka’s rescue and the three purification objectives before Old Town. After Water Dragon, regroup and proceed to Lake Dorr; Leviathan’s orbs require a different plan again.
