Nul

Original art found here: https://www.reddit.com/r/DnD/comments/9czwlb/art_doppelgangers_are_like_mood_rings/

A rare mutation, this variant of doppelganger lacks the shape-changing traits of it's kin (aside from minor facial or color changes). However, in place of this better known ability, they naturally generate an Antimagic field around themselves at all times. All magical effects, including spells and magical weapons do not function within a 10ft radius of the creature.
