Custodian of the Trove by Raoul Vitale

Actions

Multiattack. The custodian makes two slam attacks.   Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.   Slow (Recharge 5–6). The custodian targets one or more creatures it can see within 10 feet 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. In addition, the target can take either an action or a bonus action on its turn, not both. These effects last for 1 minute. A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Reactions

Defender. The custodian adds 3 to its AC against one melee attack that would hit it. To do so, the custodian must see the attacker.
