The adamantine devil is a towering mass of metal, stone, and flesh bound together into a mighty juggernaut decorated in images of death and ruin. On its chest plate is a fiendish visage whose eyes burn like hellfire. No being could be seen within its hollow frame, it seems the armor is the devil itself...

The adamantine devil, also known as a silexaversio, are lawful evil outsiders found on Acheron who are the result of evil spirits possessing a suit of armor, transforming it into a huge monstrous tank. They are born from the souls of the xenophobic, who in their fear of others sought to destroy anything different from themselves regardless of others posed any actual harm. They appear a huge-sized bulky suits of armor bound with fleshy muscles and nerves crossing the metal and stone surfaces. In fact, adamantine devils are hollow, the suit is the devil itself. Paranoid and stubborn, adamantine devils trust few and have little allies even among the ranks of other devils. Fortunately for the adamantine devils, they are usually strong enough to take care of themselves. While loathe to work for others, when it does make an alliance it will follow it until the devil gains enough strength to make such alliances unnecessary.

They make up the heavy tank troops of the menos subtype, lower planar beasts who have a disruptive effect on magic. A adamantine devil is about 18 feet tall and weigh 9600 lbs. They speak Abyssal, Celestial, and Infernal.


An adamantine devil attacks firsts and asks questions later, confident in its defenses to hold it through while it pounds away on the opponents. Its slams drain away a great deal of health allowing it to repair damage as it goes. It is powerful but very simple and straight forward in a fight.

Armored Body (Ex): An adamantine devil is composed of demonic armor, granting it a +8 armor bonus, a maximum Dex bonus of +1, an armor check penalty of -6, and 30% arcane spell failure. They may enhance their armored body or their slams as if they were manufactured armor and weapons. The default adamantine devil above possesses a +1 enhancement bonus on its slam attacks.

Disruptive Field (Ex): An aura which radiates in a 30-foot radius out from the menos disrupts the flow of magic, psionics, and any other spell or spell-like ability. Any attempts to cast within one must succeed on a caster level check DC 5 + the creature's HD or be unable to cast (the action is lost, but the spell however is not lost). It is not an antimagic field, and so magical effects originating from outside the field can still get in.

Earth Breaker (Su): An adamantine devil can sacrifice one of its maneuvers to make an attack which ripples along the ground in a straight line. As a standard action the adamantine devil deals its slam damage in a 120 ft. line to any creatures on the ground, and they must make a Reflex saving throw or fall prone, DC 10 + the level of the maneuver sacrificed + Strength modifier. A successful save halves the damage and negates the prone effect. This cannot affect creatures which are not touching the ground.

Extraordinary Health (Ex): A menos always receives maximum hit points per hit die.

Haymaker (Ex): Whenever an adamantine devil makes a melee attack the target must make a DC 15 Reflex save or fall prone.

Hinder Magic (Ex): All magical damage or healing is hindered by 50%.

Life Drain (Ex): Any successful attack against a living creature deals at +5 extra damage (already accounted for), which is absorbed as 5 point of healing per attack.

Immunities (Ex): Possessing an almost construct-like body, adamantine devils are immune to poison, sleep, paralysis, stunning, disease, death effects, critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, and energy drain. They do not possess any other construct traits.

Maneuver-Like Abilities (Ex): beg for pain (strike), binding of the earth spirit (strike), berserk soul (boost), casual shove (counter), crafter's touch (boost), disdainful shoulder (stance), endure destruction (counter), fumbling stomach smash (strike), helmet inconvenience (strike), iron fist (strike), mass impact (counter), prison of the earth spirit (strike), without thought (counter)

Smell Magic (Su): Squall devils have scent against anything which would show up with detect magic and may spend three rounds studying the scent to gain information as per the spell.

Ultraheavy (Ex): An adamantine devil is unnaturally dense and heavy. The are impossible to trip, bull rush, or otherwise move them from their position as if they were themselves an immovable rod unless the target succeeds on a DC 40 Strength check.

Unbreakable Stance (Ex): The unbreakable stance functions as a unique martial stance which follows all the normal rules for martial stances. While in unbreakable stance, all damage done against it is halved (and in the case of magic, quartered thanks to hinder magic). While in the unbreakable stance the adamantine devil can only make 5 foot steps, moving breaks the stance immediately. This is considered a 4th level maneuver.

Feats: The Golem Heart Bond feat allows the Adamantine Devil to benefit from repair spells and effects.
