Guide to Kill Hosilla and the Water Elemental on Unfair or Lower Difficulty
They are both extremely slow and the fight area has a circle to run around in both cases.
The water elemental has a table next to him – run around that! Hosillas area has a ring staircase.
Use real time combat. Use ranged weapons or spells on all characters and run away from them in a circle while stopping every now and then to shoot. Its easier to do with only 1 or 2 characters for the water elemental because of the pathfinding in that area.
Unequip armor to make your characters move faster (Seelah), make sure youre not encumbered. If you have small characters they will be so slow that they wont be able to contribute with damage but they will be fast enough to outrun Hosilla.
Neither of them can ever get close enough to hit you.
