Bring Flight and Mine Sweeper Monsters The main hazard of the dungeon is Mines. Each one will deal 160,000 damage. Therefore you want a full team of Flight and Mine Sweeper monsters. Get the Shield to Fend Off Attacks When you defeat the Demon, there will be a Shield where it is cleared. It will mitigate 95% damage for 1 Turn. Make sure you take the Shield when the enemy does a giant attack. Be careful that if the Demon gets Knockout, the Shield will not spawn.
