The Helper

The MU client has automatic hunting built in. It is different from /offattack: the Helper runs with the game open, in front of you.

What it needs

Level 80
Cost zen, and it deducts on its own

Below level 80 it does not turn on.

The difference that matters

Helper /offattack
Game open closed
Cost zen nothing
Limit none 2 h/day, up to 24 h on Diamond

The Helper is for when you are in front of the computer and do not want to keep clicking. /offattack is for when you are not.

See commands and VIP and WCoin.

Which to use

If you are leaving, /offattack. If you are staying, the Helper — it does not spend your daily limit, and the limit is the scarcest thing /offattack has.
