Cantrip. Azoth casts a cantrip.

Engulfer (Costs 2 Actions). Azoth puts his hand into his Nebulon mantle and puts out his Engulfer, using it appropriately.

Cosmic Gaze (Costs 3 Actions). Azoth fixes his gaze on one creature it can see within 15 feet of it.  Creature must succeed on a DC 21 Wisdom saving throw to not get its mind transcend into the unknown webs of cosmical realities. If it fails the saving throw Azoth casts the fear spell with 1st level slot. When effect is over, creature is immune to this ability unless Azoth uses 2nd level spell slot instead.

Void of Cosmos (Costs 4 Actions). Azoth opens his sleeves with Nebulon mantle, sucking everything that's near it to the Cosmic Void. Each creature within 20 feet of the Azoth must make a DC 17 Constitution saving throw against this magic, taking 10 (3d6) force damage on a failed save, or half as much damage on a successful one and DC 19 Strength saving throw to avoid being sucked into the Void of Cosmos. While here, creature must make a Constitution saving throw at the end of its turn taking extra 32 (9d6) cold damage on a failed save and halve as much on a successful one. Target can make another Strength saving throw during the start of its turn and as a reaction to get out of this space.
