Traits

Mimicry. The Risen Warden reproduces fragments of speech it has overheard. It does not understand language; it replays sounds. This has no mechanical effect but is deeply unsettling.
Shield Block (Reaction). When hit by a melee attack, the Risen Warden adds 2 to its AC against that attack, potentially causing it to miss. Must be wielding a shield.
