It ' s the small shit that really works . Sometimes . <| sep |> Well I think it ' s overall very complicated to explain . The description in the wiki isn ' t wrong I think , but crit is just very hard to explain . Chance to Crit when Attacking Chance to Crit when Hitting Monster ' s Chance to receive a critical strikeall are different to some degree . Assasin ' s Mark doesn ' t modify your crit chance at all , but is rather a debuff on a monster . If you have a 9 . 5 % crit weapon and 900 % increased critical strike chance which would make it 95 % in theory but no accuracy , your critical strike chance when attacking will be much lower then that . Then there ' s all those special cases . A dev explained that Diamond Shrines don ' t give you additional crit chance , but rather makes you skip crit calculations completely . Let ' s say you have a Diamond Shrine and attack a player in PvP that had an item with a mod saying 50 % less chance to receive critical strikes you would still crit him every time , because you completely skip the calculation . Crit just isn ' t the most intuitive mechanic .
