Punchbag

Help Punchbag

A punchbag mob is a level one mob with a very high number of hit points. It 
takes a long time to kill one of these mobs and it is generally best if 
several players work together to get the job done. You won't get any 
experience points for making the kill, so normally one of these mobs isn't 
targeted unless someone has given it a special item, such as a trivia point.

Run 6s3es from recall and read the sign there to discover more about these
mobs:

The mobs in these rooms are here for your personal pleasure and enjoyment.
Feel free to let out all your frustration and anger on them, but please
note that your skills/spells will not improve while doing so.

Have fun! :)
