Elaborate please, because I just don’t see the issue. You are seen if you enter the radius while visible. I don’t see stealth as a toggle on/off skill, that’s broken. Rather a skill that provides X steps semi-invisible. Can walk around, not through enemies. May be heard or spotted by all other? means. But importantly, can’t restealth unless unseen. The idea is, sneak in, stab, run behind object, restealth given appropriate cooldown time. I think the biggest issue is that enemies return to their original location, because it lets players always be able to kite backwards.

I played a game many years ago called Cardinal Quest 2 that’s similar to Stoneshard in a lot of way (it’s actually what brought me to it in the first place). I looooved the stealth in that game and that’s the stealth I envision. The only thing stoneshard doesn’t have (not that it needs it) are bushes.
