Spellslinger bugs

Looks like this should be a higher priority. Lots of skills behave differently with spellslinger.

In my case, Orb of storms, when in demon form, does not count towards buildup of energy, and also prevents me from using the invocation aspect of it. I have to cast some other skill that does build up energy (like lightning warp or arc) to allow the use of the invocation.

I may also get it unstuck with elemental weakness, however, I stopped trying and went back to a different wand to not have consistency issues.
