Hallo i wanted to report about critical rate bug on tyrants not shure if its same with s grade wepon (couse i dont have it ) but untill b grade its same. When you create character without buffs he have 84 crit rate,with buffs 212 (sword in hands) but when you place fists on crit rate falls to 109 when you take wepon away crit rate 114 and its same problem untill b grade and doesnt matter if its shadow wepon i bought even b grade from shop to check it but its still same would be nice if you could fix it thx alot
