In Diablo 3, the Wizard has a signature spell called Shock Pulse. This spell causes a (seemingly) random burst of lightning on the ground in front of you.
The problem with this is that it is a) uncontrollable, and 2) extremely limited in range. Due to the Wizard being exceptionally squishy, it's very beneficial to not let the enemies get close to me, keeping them out of range for this limited attack.
How do I make this spell worth using? Should I just avoid it altogether?
