Special Traits

• Arcane Siphon (Recharge 5-6). As a bonus action, the golem can force an enemy spellcaster that it can see within 120 feet to make a DC 16 Intelligence saving throw. On a failed save, the creature loses 1 spell slot at its lowest available level, up to level 5, and the golem gains a spell slot of the same level.
• 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.
• Spellcasting. The golem is a 12th-level spellcaster. Its spellcasting ability is Intelligence (save DC 16, +8 to hit with spell attacks). The golem has the following wizard spells prepared:

• Cantrips (at will): dancing lights, light, mage hand, minor illusion, prestidigitation
• 1st level (4 slots): feather fall, mage armor, magic missile
• 2nd level (3 slots): gust of wind, mirror image
• 3rd level (3 slots): counterspell, major image
• 4th level (3 slots): hallucinatory terrain, phantasmal killer
• 5th level (2 slots): animate objects, telekinesis
• 6th level (1 slot): circle of death

Actions

• Slash. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 17 (3d8 + 4) slashing damage.
• Arcane Flurry (Recharge 4-6). Bits of arcane paper fly from the golem in a 60 foot cone. The golem’s hit points are reduced by 8 (1d10 +3). This feature expends one spell slot of any level. Each creature within the area must make a DC 16 Dexterity saving throw or take 13 (3d8) slashing damage, 10 (3d4 +3) force damage, and 22 (4d10) psychic damage. On a successful save, the creature instead takes half damage.
