Haven't tried it yet but it looks spectacular.

I'm new to both DnD and cRPGs, I've read about what the karmic dice does but I wanted to know your opinions as well.

Does it really make it for a "better" experience? Can fights go seriously wrong or extend for a longer time when not using it? What do you all think about it?

EDIT: please read this comment by @[email protected], it explains how the dice really works, something I didn't get at first, thank you burgundymyr!
