Yeah Enochian does work a little bit differently...

Its still the same basic principle, do your Fire III, the hit Enochian, then hit Fire 4s with the Fire I on occasion to refresh your stacks quick, then Bliz 3, Bliz 4, then F3 back to F4s.

I just didn't think you'd have to turn it on first, I had thought it was supposed to be always on.

Still no timer for expiration anymore, just maintaining your stacks.
