Cosmic Blast. Ranged Spell Attack: +30 to hit, range 600 ft., one target. Hit: 140 (20d10 + 40) force damage.

Reality Sunder. The Astral Convergence tears open rifts in reality. Each creature within a 100-foot cone originating from the Astral Convergence must make a DC 30 Dexterity saving throw, taking 180 (30d10 + 30) force damage on a failed save, or half as much damage on a successful one.

Time Mastery (Recharge 5-6). The Astral Convergence alters time itself. It can take an additional turn immediately after its current turn ends.

Cosmic Shift (3/Day). As a bonus action, the Astral Convergence shifts its position within the cosmos, teleporting up to 300 feet to a location it can see within range.

Cosmic Reflection. When the Astral Convergence is targeted by a spell that requires a ranged spell attack or that forces it to make a Dexterity saving throw, it can use its reaction to redirect the spell's energy back at the caster. The caster must make a DC 30 Dexterity saving throw. On a failed save, the spell's effect is reflected back upon the caster as if they were the target. If the spell can target multiple creatures, the Astral Convergence can choose one creature affected by the spell to redirect its effect.

The Astral Convergence can take 5 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 Astral Convergence regains spent legendary actions at the start of its turn.

• Cosmic Shift. The Astral Convergence moves up to its speed without provoking opportunity attacks.

• Temporal Warp (Costs 2 Actions). The Astral Convergence targets one creature it can see within 300 feet of it. The target must succeed on a DC 30 Wisdom saving throw or be banished to a demiplane for 1 minute. While banished, the target is incapacitated and unaware of its surroundings.

• Ethereal Presence (Costs 3 Actions). The Astral Convergence shifts partially into the Ethereal Plane until the start of its next turn. While in this state, it can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

• Legendary Resistance (5/Day). If the Astral Convergence fails a saving throw, it can choose to succeed instead.
