CR 9 (XP 5,000; PB +4)
Immutable Form. The golem can't shape-shift.
Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.
Shifting Illusions. Whenever an illusion created by the golem’s Mirror Reflections moves into the same space as the golem or another such illusion, the golem can redistribute the remaining mirror image duplicates between the two in any combination. For example, if an illusion with 3 duplicates overlaps with the golem, which has 1 duplicate, the golem can decide that each will have 2 duplicates afterward. Unless a creature can see through the illusions, it doesn’t know which creature is an illusion and which is the golem after they assume separate spaces again.
Unusual Nature. The golem doesn't require air, food, drink, or sleep.
ACTIONS
Multiattack. The golem makes two Glass Sword attacks.
Glass Sword. Melee Weapon Attack: +8, reach 5 ft. Hit: 20 (3d10 + 4) slashing damage.
Mirror Reflections (1/Day). The golem creates three illusory duplicates of itself inside its space. Each illusion can move independently of the golem, using its own movement speed (30 feet). They are destroyed when they are hit by an attack. They otherwise ignore all other damage and effects. The illusions last for 1 minute, until destroyed, or until the golem is destroyed.
Immediately after using this ability, the golem and each of its illusions are affected by the mirror image spell. When an illusion is destroyed, any remaining duplicates granted by mirror image on that illusion end immediately.

QUICK REFERENCE
USING MONSTER VARIANTS
Monster variants allow the GM to adjust encounters to better match the party’s strength, narrative needs, or world-building logic. A weaker variant may represent a juvenile, wounded, or lesser specimen, while a stronger variant can serve as a leader, champion, ancient creature, or apex predator.
Variants can be used to fine-tune difficulty without changing the core identity of the monster, making them ideal for scaling encounters, reinforcing hierarchy within a faction, or creating memorable boss-style enemies. You can even use the same stat block but different variants in the same encounter if you want.
Design Note. Each monster is primarily balanced around its normal version. Weaker and stronger variants are derived adjustments and may not always preserve every tactical nuance or “feel” of the original creature. GMs are encouraged to review variants carefully and adjust abilities or tactics as needed to best suit their table.
