Intimidation is a very hard skill to work up. It's very slow going at the beggining and increases faster as you skill goes up. This spell is a Fear spell in essense without mana and is intantanious. I didn't catch this skill up to my level till I hit level 35. It does prove to be usefull, as it allows for Fear kiting.

Intimidation isnt too bad to skill up untill 180 then OMG its 1000+ clicks per skill no kidding. At 191 skill + 15% mask I kick about 80% of the time and miss about 90% of the time on the kick, when I have to fear kite in ldon :( buuuut I can solo ice giants and hardly take any damage when using intimidate, because theyre easier to hit.
