Since we got alot of new dungeons after corean open beta ( and orsha ), i would like to know if i still need grind until lvl167 to pass the deadzone wall.
if you save enough exp cards i think you can pass that area.
No.
Missions and dungeons around that level will occupy you long enough that you don’t have to go there for a week.
You can if you want to, for a few levels.
Collect your social security food stamp cards and you can pass it entirely.
