Multiattack

The guardian makes two Moonlight Slam attacks.

Moonlight Slam

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) bludgeoning damage plus 4 (1d8) radiant damage.

Moonlight Blast (Recharge 5-6)

The guardian unleashes a magical blast of moonlight in a line 60 feet long and 5 feet wide. Each creature in that area must make a DC 14 Dexterity saving throw. Creatures that aren't in their true form have disadvantage on the save. On a failed save, a creature takes 22 (5d8) radiant damage, and if it isn't in its true form, it is forced into its true form and can't change forms until the end of the guardian's next turn. On a successful save, a creature takes half as much damage only.
