How much damage does your shocking touch do at that level?
With 28 Int shocking touch does 45-50 air damage for 1 AP. I only killed the worm with one shock as the magisters had almost finished it off anyway...
By comparison chain lightning (3 AP) and electric fence (2 AP) both do exactly double at 90-100 damage so in terms of damage to one enemy shocking touch is the same (per AP) as electric fence and both are better than chain lightning. You have to be closer of course but it is a powerful skill.
