Everytime i try to cast a spell on certain npcs it doesn't do anything just the animation. So like if i tried to cast ice barrage on a certain npc it just displays the animation and then doesn't deal any damage or grant any xp. The other weird thing is then when you try to use melee or range it doesn't let you attack either. It just shows the animation but doesn't actually deal any damage, or grant xp... any ideas on how to fix it?
