Merztorlegon

Frequency once per round

Effect The vordines fire projectiles, dealing 7d8 piercing damage to creatures in a 10-foot burst within 200 feet (DC 38 reflex save).

A merztorlegon and their crew can creatures at a range of 120 feet and don't take a penalty for not sharing a language with the target.

A shoulder ballista is an extension of the merztorlegon's body, functioning as a siege weapon that shares the demon's space, can't be targeted, and ceases to function after the merztorlegon's death. Either the merztorlegon or their siege crew can Aim or Load the ballista, but only the crew can Launch it.

Aim 1 80 feet, minimum distance 30 feet

Load 1 (manipulate) 1 time

Launch 1 (attack, magical, manipulate, range increment 120 feet, unholy) 8d12 piercing, single target, DC 41 reflex

Several vordines inhabit the siege tower and are an extension of the merztorlegon, use the devil's skill modifiers, and can't be targeted individually. On the siege devil's turn, the crew can take 2 actions that can be used only to launch an Arrow Volley; ; or to Aim, Load, or Launch the devil's shoulder ballista. Once the merztorlegon is reduced to half their maximum Hit Points, the siege crew is injured and takes only 1 action per turn.

A merztorlegon's melee Strikes deal an additional 3d12 untyped damage to items and structures.

The merztorlegon gathers a willing adjacent troop into their siege tower or shunts a stored troop into an adjacent space. The devil can store only one troop at a time, during which time the troop can't take actions, can't be targeted by effects, can be transported by the devil's translocate spell, and increases the damage dealt by Arrow Volley by 2d8. If the merztorlegon is defeated, any stored troop immediately reappears in or adjacent to the siege devil's space.
