Special Traits

• Possession. The possessed armor can be donned like an ordinary suit of armor, functioning as a suit of +1 plate armor. While worn by a creature, the armor can’t take actions and perceives through the senses of its wearer, in addition to its own blindsight. Resistances and immunities only apply to the armor itself, not the wearer. If a creature dons or partially dons the armor, the creature must make a DC 19 Charisma saving throw. The creature is unaware that it is resisting possession. On a failed saving throw, the creature is possessed by the armor until targeted by a dispel evil and good spell, or similar magic. If the creature succeeds on the saving throw, it must make another saving throw each hour until it doffs the armor. While possessed, the creature is completely under the armor‘s control.
• Aura of Evil Arcane. The armor, and any creature wearing it, can be detected by a detect evil and good spell, or similar magic, as though it were a fiend. It can also be detected by a detect magic spell, seeming to be a suit of +1 plate armor.
• False Appearance. While the armor remains motionless, it is indistinguishable from a normal suit of armor.
• Fiendish Dismissal. If the armor is targeted by a dispel evil and good spell, or similar effect, it must save as though it were a demon. If it fails its saving throw against the dismissal effect, the possessing demon is sent to its home plane for 1 hour, and the armor becomes a mundane suit of plate armor for that duration. If the armor is destroyed while the demon is banished, the demon is permanently banished.
• Shadow Strikes. Melee weapon attacks made by the armor, or a creature wearing it, deal an extra 7 (2d6) psychic damage (already included in the armor’s attacks).
