Special Ability (1/day)

As an action, the voidskulker taps into the chaotic energies of the void, infusing its weapon with unstable astral energy. The next successful melee weapon attack made by the voidskulker within the next minute deals an additional 3d6 force damage. Additionally, the target must make a DC 12 Strength saving throw or be pushed 10 feet away from the voidskulker and knocked prone. Once the void infusion ability is used, the voidskulker cannot use it again until it completes a long rest.

Space Tactics: Voidskulkers are skilled at hit-and-run tactics, taking advantage of their small size and nimbleness to outmaneuver foes. They favor ambushes and coordinate attacks from multiple angles, using their mobility to quickly retreat or reposition in zero gravity environments. They often employ crude jetpacks or grappling hooks to gain the upper hand in space combat.

• Tentacle Attack: The Voidborn Leviathan makes a tentacle attack.
• Break Free (Costs 2 Actions): The Voidborn Leviathan ends one grapple, restraint, or immobilizing effect on itself.
• Warp Reality (Costs 3 Actions): The Voidborn Leviathan releases a pulse of otherworldly energy, causing the terrain in a 30-foot radius around it to become difficult terrain. Creatures within that area must make a DC 18 Wisdom saving throw or be confused (as the confusion spell) until the end of their next turn.

Special Ability (1/day)

Cosmic Devourer: The Voidborn Leviathan opens a tear in reality, creating a 30-foot-radius sphere of darkness centered on a point it can see within 120 feet.

At the start of the Voidborn Leviathan’s next turn, all creatures within the area must make a DC 21 Dexterity saving throw, taking 56 (16d6) force damage on a failed save, or half as much damage on a successful one.
