- Cast the buffs from Thrall and Wrynn on themselves instead of the player. This prevents interrupting spellcasting of the player during battle.
- Override "EnterEvadeMode" for Thrall and Wrynn AI in order to prevent removing their auras on evade.
- Remove the spell script "spell_undercity_buffs" as it is not needed anymore (the players only get the aura when near Thrall or Wrynn)
