Q: Dear Sage,
On what kinds of successful grapple checks do armor spikes deal damage?
A: The damage from armor spikes is dealt when you make a successful grapple check made for the purpose of dealing damage (the “Damage Your Opponent” option, PHB p156).
About the Author
The Sage is a mammal classified in the bear family, Ursidae, native to central and southern China. Debate continues as to whether he is truly a bear or more related to the raccoon rather than the bear, or perhaps in a family of his own. When not eating bamboo and answering rules questions, he works under the nom de plume of Andy Collins as an RPG developer in Wizards of the Coast R&D, where his development credits include Complete Mage, Dragon Magic, and the Player's Handbook v.3.5. He can be easily recognized by his large, distinctive black patches around the eyes, ears and on his rotund body.
