Horrid Mutilation works like you've just stated :P Previously, it had inifinte stacking of % damage, so PrimusMobileVzla gave me this idea, so that Odium still does well in prolonged fights but just slightly and not sickly.

And the Dark energy costs are that high just to encourage Odium to play agressively (since he gains most of dark energy in combat).

And each casts of Ethereal Fire don't cost any additional dark energy.

If you've got any further questions, feel free to ask. And thank you for feedback ^^
