Golem Companion

Once you reach 10th level in this class, the golem is immune to any spell or effect that would alter its form. When you cast a wizard spell targeting your golem, you can choose for the spell to ignore this trait until immediately after the spell ends.

Once you reach 14th level in this class, the golem has advantage on saving throws it makes against spells and other magical effects.

Melee Weapon Attack: your spell attack modifier to hit, reach 5 ft., one target. Hit: 1d8 + PB bludgeoning damage
