I thought I checked on my critchance and found that wearing dagger does nothing to my crit chance at all. Now it is either bugged or the chracter UI is totally messed up due to differenciating between weapon crit and crit (yeah, their wording. not mine). this might lead to the passive not being bugged but in that case nobody can tell because overall critchance is nowhere to read so ...I call bugged unless someone proves otherwise.
