Known issues:
- encounter doesn't start immediately after you enter the room, you need to go closer
- players standing outside of the room are not turned Insane after 15 seconds
- encounter resets if the last living player is gripped by Constrictor Tentacle or encased in Hodir's Flash Freeze
- Hodir won't freeze multiple players when they die at the same moment
- Flash Freeze missile (64176) won't hit anybody, probably cast too soon (cosmetic issue)
- there are some unused spells, don't know when or why they should be cast
- some spell animations hit multiple players, but they shouldn't do that
