PvE and monsters energy

The bug is that you can use the skills even if you have no energy. Well it still gets lower but... I don't think it's normal to have less than 0 energy. Or am I mistaking?

It's working fine for me. Which skill are you trying to use, and what monster type is it?

I'm using Bubble Blast. And my monster is cute

Maybe just my monster is bugful

I've had that happen to me too, with both my evil and normal monster. They were using claw of evil and big tackle, respectively.

Ah HAH! I think I found it. I know I definitely found something and my cute monster isn't doing it now. Quite the odd bug, it was some kind of anomaly or something. The game's so big now that it was doing weird things and blah blah.

Tell me if this happens to anyone again. I couldn't get it to work with evil, so I went to cute and bubble blast did it. I think it was 'cuz of the low-energy attacks.
