The Ancient Void Dragon can take 3 legendary actions per round, choosing from the options below. Only one legendary action can be used at a time, and it resets at the start of the dragon’s turn.

1. Detect

• Action: The dragon makes a Wisdom (Perception) check.

• Purpose: Helps the dragon locate hidden, invisible, or stealthy creatures.

• Range: Self

• Notes: Useful for maintaining battlefield awareness, especially against invisible or elusive foes.

2. Void Step

• Action: Teleport up to 60 ft. to an unoccupied space it can see.

• Purpose: Allows sudden repositioning, escaping tight situations, or surprising enemies.

• Notes: Can move in or out of melee, avoid area effects, or flank enemies for advantage.

3. Wing Attack (Costs 2 Actions)

• Action: The dragon beats its massive wings.

• Effect: Each creature within 15 ft. must succeed on a DC 22 Strength saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone.

• Movement: The dragon can also fly up to half its flying speed after the attack.

• Purpose: Provides crowd control, disrupts enemy formations, and combines mobility with offense.

4. Rift Grasp (Costs 2 Actions)

• Action: The dragon targets up to 3 creatures within 60 ft. and attempts to restrain them.

• Effect: Each target must succeed on a DC 22 Strength or Dexterity saving throw or be restrained until the start of the dragon’s next turn.

• Purpose: This represents the dragon using its void powers to manipulate or hold multiple foes at once, perfect for isolating enemies or controlling the battlefield.

Notes on Legendary Actions:

• The dragon can mix and match actions, using 1, 2, or 3 actions per turn, depending on the cost.

• These legendary actions are in addition to its normal turn, allowing the Ancient Void Dragon to remain a deadly, unpredictable force.

• Void Step is particularly thematic: unlike a reaction, legendary actions allow it to move after other creatures act, giving it control over the timing of its teleportation.
