> I'd suggest some arrows/lines or whatever to signify requirements or at least relations between skills
Yeah, I'll do that, I do need to up my UI to make it make more sense at a glance.

There's nothing like that except for the message you get when you level up. I do need to that, UI indicators for when attribute/skill upgrade is available.

You're absolutely right. I didn't like the blend of colors my previous status fx system did (mixing the monster's base color with the status color) so I made affected characters the status' flat color (fire=orange, cold=blue, lightning=yellow, poison=green), but I do have to change that.
Thanks for playing, diablo bro.
