Traits and Actions

Multi-Headed Armor

Trait
Hydra Heads Custom
The Warplate has five heads. While it has more than one head, it has advantage on saving throws against being blinded, deafened, stunned, and knocked unconscious. It cannot be flanked while more than one head remains.

Head Regrowth

Trait
Hydra Multiple Heads Custom
When the Warplate takes 25 or more damage in a single turn and has fewer than five heads, one severed head regrows and the Warplate regains 10 hit points. If it takes fire damage, this trait doesn't function until the end of its next turn.

Animated Menace

Trait
Construct Type Custom
The Warplate is an empty suit of armor animated by bound spirits. It doesn't require air, food, drink, or sleep.

Construct Type. is_custom false; standard construct traits apply.

Multiattack

Action
The Warplate makes as many bite attacks as it has heads.

Bite

Action
Attack Roll Custom
Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 5) piercing damage plus 4 (1d8) force damage.

Wail of the Hollow Legion (Recharge 5-6)

Action
Frightened Condition Custom
Each of the Warplate's heads emits a discordant shriek. Each creature within 30 feet must make a DC 15 Wisdom saving throw. On a failure, a creature takes 22 (4d10) psychic damage and is frightened for 1 minute. On a success, it takes half damage and isn't frightened. A frightened creature can repeat the save at the end of each of its turns.

Coiling Advance

Bonus Action
The Warplate moves up to half its speed without provoking opportunity attacks.

Interposing Helm

Reaction
Reaction Custom
When a creature within 10 feet of the Warplate is hit by an attack, one head interposes itself, granting that creature a +3 bonus to AC against the attack, potentially causing it to miss. The head is destroyed on a miss if the attack's total equals or exceeds 18.

Reaction. is_custom false; standard reaction timing.
