Multiattack

The marid makes two trident attacks. One of these can be replaced with a net attack.

Trident

Melee or Ranged Weapon Attack: +10 to hit, reach 10 ft. or range 20/60 ft., one target. Hit: 13 (2d6 + 6) piercing damage plus 5 (1d10) lightning damage. If thrown the trident returns to the marids hand.

Net

Ranged Weapon Attack: +10 to hit, range 5/15 ft., one target. Hit: A Large Medium or Small target is restrained until it is freed. A creature can use its action to make a DC 18 Strength check freeing itself or another creature within its reach on a success. The net is an object with AC 10 20 hit points vulnerability to slashing damage and immunity to bludgeoning poison and psychic damage.
