Q: Dear Sage,
Does an attacker have to damage a dragon shaman (PHB II, 11) to be affected by the energy shield draconic aura, or just hit him? And if so, if the attack roll is enough to hit his touch AC, should that also trigger the energy shield?
A: The attack must successfully hit the dragon shaman -- that is, the attack roll must equal or exceed your Armor Class -- to trigger the effect of the energy shield. Dealing damage isn’t necessary.
If the attack is a melee touch attack, it need only hit your touch AC, but a normal attack that hits your touch AC but not your normal AC doesn’t trigger the energy shield.

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.
