DESC: Disguise is the skill to make a person or object appear as something other that what it is. The user sets the difficulty and any that see the disguised person make a roll to notice it is not the real thing.

A DM may modify either side of the challenge depending on circumstance. Distance to targets (viewers), Familiarity with the real object (disguise a human child as a Kobold when the humans have not seen a Kobold) and quality of the materials used in the disguise.
