first you have to decide if you want a str or dex build. depends on what skills you want to use too. and how useful you want to be at endgame bosses.

my stats is
str 395
dex 1110
focus 150
vit 555
needed more vit for yule boss to stay alive against aoe attacks
for skills
Riposte
Shadowstrike
quickstrike
dubble attack
lifesteal

need help fixing this build to more of free for all battles on bosses and mobs thx
