Chad — Warforged Guardian

Warforged Resilience. The warforged has advantage on saving throws against being poisoned and is immune to disease. Magic can’t put it to sleep.

Mounted Platform. Chad’s back is reinforced with climbing grips and support plating, allowing a Small creature to ride him comfortably. Zibby Gearlock often rides on Chad during travel or combat.

Siege Monster. Chad the warforged deals double damage to objects and structures.

Multiattack. The warforged makes two attacks from the following.

Slam. Melee Weapon Attack: +18 to hit, reach 20 ft., one target. Hit: 29 (3d12 + 10) bludgeoning damage, and the colossus can push the target up to 20 feet away from it.

Eldritch Turret. Ranged Spell Attack: +18 to hit, range 300 ft., one target. Hit: 18 (4d8) force damage, and if the target is a creature, it is knocked prone.

Incinerating Beam (charge 1 pre-day). The colossus fires a beam of light in a 150-foot line that is 10 feet wide. Each creature in the line must make a DC 26 Dexterity saving throw, taking 60 (11d10) radiant damage on a failed save, or half as much damage on a successful one. A creature reduced to 0 hit points by this beam is disintegrated, leaving behind anything it was wearing or carrying.

Protection. When an attacker the warforged can see makes an attack roll against a creature within 5 feet of the warforged, the warforged can impose disadvantage on the attack roll.
