Aspect of Raziel, The Rending Infinity

Cosmic Weapons. Raziel's weapon attacks are magical. When he hits with any weapon, the weapon deals an extra 6d8 radiant damage (included in the attack).

Divine Awareness. Raziel knows if it hears a lie.

Innate Spellcasting. The Rending Infinity's spellcasting ability is Charisma (spell save DC 25). It can innately cast the following spells, requiring no material components:

At will: control weather, mirror image (self only), resurrection

3/day each: Fire Storm, Disintegrate, Earthquake, Meteor Swarm, Reverse Gravity

1/day each: Time Stop, Whirlwind

Magic Resistance. Raziel has advantage on saving throws against spells and other magical effects.

Multiattack. The Rending Infinity makes two attacks with his hammer.

Starfall. Melee Weapon Attack: +18 to hit, reach 5 ft., one target. Hit: 22 (2d8+ 15) bludgeoning damage plus 25 (6d8) radiant damage.

Hammer Throw. Raziel releases Starfall to throw at an opponent within 30 feet of it. The Rending Infinity can mentally command it as a bonus action to fly up to 50 feet and either make one attack against a target or return to Raziel's hands. If the hammer falls to the ground without being summoned back to Raziel's hand, it will emit is own gravity and be unable to be moved except by Raziel himself.

Gravity Bomb. Raziel can raise Starfall above his head and bestow it with the gravitational pull of a black hole, and release it with a powerful controlled burst. Any creatures within 50 feet must make a DC 20 constitution saving throw or be thrown back 15 feet and be knocked prone, whilst taking 25 points of bludgeoning damage.

Raziel can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Rending Infinity regains spent legendary actions at the start of its turn.

Teleport. Raziel magically teleports, along with any equipment it is wearing or carrying,  to any unoccupied space it can see.

Searing Burst (Costs 2 Actions). Raziel emits magical, divine energy. Each creature of its choice in a 30-foot radius must make a DC 26 Dexterity saving throw, taking  (19d6+40) force damage  (19d6+40) radiant damage on a failed save, or be blinded for one turn on a successful one. If a targeted creature fails the save, (or is a summoned creature, construct, elemental, fiend, etc.) if reduced to 0 hit points, they are instantly disintegrated and can only be brought back with a resurrection spell.

Blinding Gaze (Costs 3 Actions). The Rending Infinity targets one creature it can see within 120 feet of it. If the target can see it, the target must succeed on a DC 21 Constitution saving throw or be blinded until magic such as the lesser restoration spell removes the blindness.
