Special Abilities

Fractalize. When the golem is reduced to 0 hp, it explodes. Each creature within 5 feet of it, except for other fractal golems, must succeed on a DC 14 Dexterity saving throw or take 4 (1d8) force damage and be pushed back 5 feet. Two duplicate fractal golems appear in the golem's space and the nearest unoccupied space, each with the same statistics as the original fractal golem, except one size smaller. When a Tiny duplicate of the golem is reduced to 0 hp, it explodes and doesn't duplicate. All duplicates act on the same initiative.

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

Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.

Magic Weapons. The golem's weapon attacks are magical.
