Q: Dear Sage,
Does the dragon shaman’s vigor draconic aura (PHB II, 13) affect warforged? Is the healing halved?
A: Yes and yes.
The draconic aura is a supernatural ability, and warforged gain only half the normal healing from supernatural abilities that heal hit point or ability score damage.
This means that a warforged is completely unaffected by the vigor aura until its bonus reaches 2 (since half of 1 rounded down is 0). While damage rolls and hit point rolls have a minimum of 1 (PHB, 304: “Rounding Fractions”), no such general rule applies to healing effects.
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.
