The summon draconic spirit spell states (FToD, p. 21):
When you cast this spell, choose a family of dragon: chromatic, gem, or metallic. The creature resembles a dragon of the chosen family, which determines certain traits in its stat block.
Does the Chromatic Draconic Spirit get resistance to Acid, Cold, Fire, Lightning, and Poison? Or is it a choice of one damage type?
Some of my fellow DMs believe that because the spell says the creature resembles a dragon of the chosen family, a chromatic spirit would have to look like one of the Chromatic dragons (Black for example) and that it would only get resistance to the damage usually associated with that type of chromatic dragon (Acid for Black dragons).
