4-level Conjuration
You conjure raw materials and sculpt them into a construct, appearing in an unoccupied space you can see within range. It uses the Golem Spirit stat block, and you select either the Flesh, Stone, or Iron option when you cast the spell. The creature disappears when it drops to 0 hit points or when the spell ends. The creature is an ally to you and your companions. In combat, it shares your initiative count, and takes its turn immediately after yours. It obeys your verbal commands. If you don’t issue any command, it takes the Dodge action and moves only to avoid hazards.
Multiattack. The golem makes a number of attacks equal to half this spell's level (rounded down). Only one can be a Poisonous Gas attack, if available. Slam. Melee Weapon Attack: your spell attack modifier to hit, reach 5 ft., one target. Hit: 1d8 + 4 + the spell's level bludgeoning damage. Poisonous Gas (Iron Only). All other creatures within 5 feet must make a Constitution saving throw against your spell save DC. On a failure, a creature takes 1d12 + the spell's level poison damage and is poisoned until the end of its next turn.
