yeah, possible
Yes it's possible if you are z$x
W/ GoF?
130 attack is possible in my gear, and plenty of sins have things like 4atk rings, attack level ds's/ws belts etc, so I would say it's very possible.
base attack lv in full r8 is 90 with ascended supreme robe,
lel base atk lv in full r8 and ascended supreme robe total 90?i don't think so.
