[Dimitar Kordev]

Hello everyone! I need an advise, is there any specialist at  kamaels? Im arbalester and i wonder what are the conditions to cast that "trigger" buff?  Do i need  SA on the  weapon?  For example can i cast  trigger with  D weapon+4 ?  Ty in advance !

The more crit you have, the more often the trigger goes off. Ideally, you should have a C grade rapier with a CA focus. The 80 crit difference is felt very strongly
