Traits

Fleeting Anger. If another creature deals damage to the Returned, the Returned makes attack rolls with advantage until the end of its next turn.

Turn Resistance. The Returned has advantage on saving throws against any effect that turns undead.

Unreadable Face. The Returned is immune to any effect that would sense its emotions or read its thoughts. Wisdom (Insight) checks to ascertain the Returned's intentions or sincerity are made with disadvantage.
