Ogre club

The Ogre club is a common drop from an ogress level 69, an Ogress Warrior level 86, or an Ogress Champion level 99. Wielding it requires 5 attack.

Despite its size and prominence, the club is not a formidable weapon.

Glitches
When looking at the club in your inventory or bank it appears as if a part of the club has been cut off. It is unclear whether this was meant to happen but it is likely that it is a mistake by Jagex. This glitch has been fixed as of 24 June 2010.

It is also unclear whether this club is supposed to hit two squares away from a target, but it appears as it does when you attack with it.
