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

Innate Spellcasting. The algorith’s innate spellcasting ability is Charisma (spell save DC 16). It can innately cast the following spells, requiring no material components:

At will: aid, blur, detect magic, dimension door

5/day each: dispel magic

1/day: commune (5 questions), wall of force

Actions

Multiattack. The algorith makes two logic razor attacks.

Logic Razor. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 31 (4d12 + 5) force damage.

Cone of Negation (Recharge 5-6). An algorith can project a cone of null energy. Targets inside the 30 foot cone take 42 (12d6) force damage and suffer the effect of a dispel magic spell. A successful DC 16 Dexterity saving throw reduces the damage to half and negates the dispel magic effect on that target.

Reality Bomb (5/Day). The algorith can summon forth a tiny rune of law and throw it as a weapon. Any creature within 30 feet of the square where the reality bomb lands takes 21 (6d6) force damage and is stunned until the start of the algorith’s next turn. A target that makes a successful DC 16 Dexterity saving throw takes half damage and isn’t stunned.
