A cestus is a sturdy leather or wicker sleeve and fingerless glove which attaches to your arm and hand. It has striking plates and/or spikes which deal lethal damage. You may carry objects in a hand wearing a cestus. You may wield weapons in a hand wearing a cestus, but take a -2 penalty to hit. You may use that hand for Dex-based skill rolls, but such rolls take a -2 penalty as well. Donning or removing a cestus takes a full round action. The Cestus belongs to the "Monk" and "Close" weapons groups.
