Still masq build for me in PVP. Invisibility + fatal menace = stun, then burst. If doesnt die then choose other target. MVP build is effective if you are whaler in my opinion.
use your copy 3rd job skill name "Soul Capturing" and go to Training Ground where u test DPS and pick the MVP then copy all of them u will get all of the skills permanent.
I think its better not to use converter since your skills are shadow type and not alot of people have shadow reduc. I just tested this one too and base on my observation, not using converter deals more damage. Youcan try to, let me know 🤙
