Things Burst of Glacial Wrath will freeze:
Most humans/humanoids
Animals
Elementals
Mephits
Reptiles (kobolds/troglodytes)...usually
Demons/devils
Most giants, orcs, monstrous humanoids
But there are some interesting exceptions:
It normally freezes minotaurs and ogres, but won't freeze them in madstone crater, where they have a buff giving them immunity to mind altering spells
It can freeze the fiendish kobolds in quests like Creeping Death, but not in Legendary Shroud, where they have the Mandate of Shavarath buff
It can somehow freeze ice themed monsters like ice mephits and winter wolves, even though they do not take damage from the spell
Notice a pattern? Burst of Glacial Wrath only freezes things that can be charmed!
