Ok just learned the magic explosion(or something similar, I forget the exact name) skill after becoming a magician and Every time I try to use it it acts like I havent pressed anything. I am using a whip which is a soft weapon and soft weapons are able to use that skill. So whats wrong?

were you in auto-fighting model?

Did you select a target? You have to left Click on the monster before pressing the hotkey.

yeah a monster was selected because it wouoldnt do anything when I try to use that skill but then when I press the hotkey for a different one it works. =/
