Armor SpikesYou can have spikes added to your armor. They allow you to deal 1d6 points of piercing damage (x2 crit) with a successful grapple attack. The spikes count as a martial weapon. If you are not proficient with them, you suffer a -4 penalty on grapple checks when you try to use them. You can also make a regular melee attack (or off-hand attack) with the spikes, and they count as a light weapon in this case.
An enhancement bonus on a suit of armor does not improve the spikes' effectiveness, but the spikes can be made into magic weapons in their own right.
