AVATAR OF THE MOUTHLESS GOD

Eldritch Form. The Avatar occupies a 60-ft. cube but can distort space; it can attack through walls or floors as if it were adjacent. Creatures can occupy its space (difficult terrain, start turn DC 25 Wis save or gain 1 point of Eldritch Revelation).

Reality Breaker. The Avatar ignores all resistances and immunities of creatures it can see except to force and radiant.

Aura of Revelation (Mythic). 60-ft. radius; creatures starting their turn here make a DC 23 Wis save or gain 1 Eldritch Revelation point (3 = short-term madness; 5 = DM control).

Mythic Trait – Phase II: The Awakening.
When reduced to 0 HP, the Avatar doesn’t die. It splits open into a radiant abyss, regaining 300 HP, reshaping the world into impossible angles.
The sky tears. Colors bleed wrong. Gravity convulses. Time shudders backward one heartbeat.
All creatures within 120 ft. make a DC 24 Wis save or take 45 (10d8) psychic damage and are stunned until the end of their next turn.
Phase II unlocks its Mythic Actions and additional traits below.

Multiattack. 3 attacks of any type below.

Tentacle of Unmaking. Melee Weapon Attack: +19 to hit, reach 30 ft., one target. Hit: 36 (4d12 + 10) bludgeoning + 18 (4d8) psychic damage, and the target must succeed on a DC 23 Con save or lose concentration and 1 prepared spell of your choice.

Rend Reality (Recharge 5–6). The Avatar rips the world open in a 40-ft. radius. Each creature must make a DC 23 Dex save or take 72 (16d8) force damage and be banished to a nightmare fragment until the end of its next turn (incapacitated).

Whisper of Oblivion. Targets up to three creatures it can see. Each must succeed on a DC 23 Wis save or take 45 (10d8) psychic damage and be silenced (can’t speak or cast verbal spells) for 1 minute.

Unmake Faith. The Avatar targets a creature that can cast spells within 60 ft. The target makes a DC 24 Cha save or one of its active magical effects ends (dispel magic, 9th level equivalent) and it takes 27 (6d8) psychic damage.

Warp Step. The Avatar teleports up to 100 ft to an unoccupied space it can see, passing through matter and creatures without provoking opportunity attacks. Each creature it passes through must make a DC 23 Dex save or take 21 (6d6) force damage.

Fold Space. When a creature moves within 30 ft of the Avatar, it forces that creature to make a DC 23 Charisma save or be teleported to a random point within 60 ft and take 28 (8d6) force damage.

Eye of Madness. When the Avatar is hit by a melee attack, it locks eyes with the attacker. The creature must succeed on a DC 24 Wis save or take 36 (8d8) psychic damage and gain 1 Eldritch Revelation point.
