Necrofex Colossus (5e Creature)
From D&D Wiki
Gargantuan construct, neutral evil
Damage Resistances cold; bludgeoning, piercing and slashing from nonmagical attacks that aren't adamantine
False Appearance. While the necrofex colossus is motionless, it is indistinguishable from the wreckage of a galleon.
Immutable Form. The colossus is immune to any spell or effect that would alter its form.
Siege Monster. The colossus deals double damage to objects and structures.
Multiattack. The colossus can use its Frightful Presence. It then makes three attacks.
Slam. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 35 (6d8 + 8) bludgeoning damage.
Hand Cannon. Ranged Weapon Attack: +13 to hit, reach 60/300 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage plus 10 (3d6) fire damage.
Frightful Presence. Each creature of the colossus's choice that is within 60 feet of the colossus and aware of it must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the colossus's Frightful Presence for the next 24 hours.
Abandon Ship! (1/Day). The colossus summons 20 zombies in unoccupied spaces within 30 feet of it.
Volley Fire (Recharge 5-6). The colossus makes three attacks with its hand cannon.
A colossal walking abomination of galleon-torn wood, iron, and man-flesh, relentlessly driven by a vortex of necromantic energy. The necrofex colossus is a rare and prized minion of destruction for undead pirates and sea dwelling evil wizards.
Humanoid Ship of Terror. The unhallowed form of the necrofex colossus is one of the most terrifying anathemas known to arcane experts. Varying in composition, they always hold true to the same basic form, a monstrous humanoid shape akin to a giant, fashioned upon a frame of galley-torn timber, iron, or bones, onto which the ‘flesh’ and musculature of the dead has been bound and shaped, with scores of human corpses used in their creation. These gargantuan monstrosities fear neither pain nor injury, for they are walking vortexes of otherwordly energy around which the souls of the damned howl and against which few mortals can stand. With so much unholy power concentrated in their forms, a necrofex colossus is no mere mindless thrall, but possesses a malicious will and dark appetite of its own, often outlasting its creator or even proving their undoing should its master’s control slip even for a moment.
