my trait dumb stupid has killed my skill pool in the midst of a battle to the death



On a more serious note, what happened in the screenshot was that I got the curse statuses Crippling Muysig (which lowers SKI/CEL) and Noshka's Famine (STR/WIL) then proceeded to weapon-swap, which lead to losing my skills in the middle of fighting.

It looks like the game assumed that I didn't have the WIL/SKI for these two slots because of the curse statuses dropping these stats, so it removed them in-battle.

This seems to happen with any other battle effects that drop your stats, so long as you swap your weapon afterwards. I imagine it's not intentional to lose your skill slots in battle.

This happens to Tomes too, due to the Talent.

The game should no longer be doing this in the middle of battles.
