Multiattack

The irid uses its Gossip. It then uses its Iridescent Blast once.

Iridescent Blast

Ranged Spell Attack: +5 to hit, range 60 ft., one target. Hit: 7 (2d6) radiant damage.

Gossip

The irid spouts gossip and exaggerated truths about a target it can see within 30 feet. If the target is hostile, it must succeed on a DC 13 Charisma saving throw or have disadvantage on its next attack roll. If the target is friendly, it has advantage on its next attack roll.

Invisibility

The irid magically turns invisible until it attacks or uses Gossip, or until its concentration ends (as if concentrating on a spell). Any equipment the irid wears or carries is invisible with it.
