Slam - Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.
Slow - The golem targets one or more creatures it can see within 10 ft. of it. Each target must make a DC 17 Wisdom saving throw against this magic. On a failed save, a target can't use reactions, its speed is halved, and it can't make more than one attack on its turn.

A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
