Algorith

Construct Nature. The algorith doesn't require air, food, drink, or sleep.

Immutable Form. The algorith is immune to any spell or effect that would alter its form.

Logic Razor. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) force damage.

Cone of Negation (Recharge 5-6). The algorith projects null energy in a 30-foot cone. Each creature in the area must make a DC 16 Dexterity saving throw. On a failure, a creature takes 33 (6d10) force damage and any spell of 4th level or lower on the creature ends, as if it had been the target of a dispel magic spell. On a success, a creature takes half the damage and spells on it don't end.

Reality Bomb (5/Day). The algorith summons and throws a tiny rune of law at a point it can see within 100 feet. The rune explodes on impact. Each creature within 30 feet of where the rune landed must make a DC 16 Dexterity saving throw. On a failure, a creature takes 27 (5d10) force damage and is stunned until the end of its next turn. On a success, a creature takes half the damage and isn't stunned.

Spellcasting. The algorith casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability (spell save DC 16): At will: bless, detect magic, dimension door, dispel magic 1/day each: commune (as an action), wall of force
