KRAKEN's floor mercifully lacks any GHOSTS, but large groups of WATERS will appear from time to time. They can wear down a party quickly, so give them everything you have (including ICE3, if you have it). The other encounters are all fairly easy, and are a good time to use the Heal Staff to prepare for the fight with KRAKEN if you're low on HEAL Potions and CURE or HEAL Spells.
