The Tower of Owen is by far the longest dungeon you've seen so far. You'll want to take along the Teleport Spell from the Village of the Ancients just in case things go poorly. There are no Elemental resistances or weaknesses to worry about in the tower, but make sure you pace yourself and don't waste resources. The Monsters here tend to cast a lot of Spells, so you never know what you might be hit with.
