Bolt of ice does not make an AoE ice effects. It only creates a very small ice spot. Barley enough to cover one meter of ground or less.
Enemies do avoid it and walk around it.
There is no spell that gives burst of multiple ice shards.
Ice elemental is level 9 spell. And you cant aim it at water and make it create AoE surface. It just does that when it dies.
Seems to me you have no idea what you are talking about at all.
Quite funny seeing how you are in such a hurry to start every post of yours with various statements of others not knowing what they are talking about.
