It seems self explanatory, but I setup a mouse-over macro to place living bomb on the target that my mouse is over...but it didnt work.
#showtooltip Living Bomb
/cast [@mouseover, harm] [ ] Living Bomb
So, what exactly is a mouseover macro, how does it work, how do I set it up correctly, and do I need to do anything like hit a key for it to work? I apologize for being a noob about this, but I've never used macros much.
