Alluring Thrum (Recharge 5-6).

The emissary emits a dreadful yet alluring hum. Each creature within 20 feet of the emissary that can hear it and that isn't an aberration must succeed on a DC 14 Constitution saving throw or be charmed for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Crystal Spores (Recharge 6).

A 15-foot-radius cloud of toxic crystalline spores extends out from the emissary. The spores spread around corners. Each creature in the area must succeed on a DC 14 Constitution saving throw or become poisoned. While poisoned in this way, a creature takes 11 (2d10) poison damage at the start of each of its turns. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
