Befouling Aura (Su)
Wormwood is surrounded by an aura of necromantic energy that can render all drinkable liquids (including potions, elixirs, extracts, and mutagens) within 100 ft. contaminated and poisonous to drink. Magic liquids receive a DC 25 Fortitude save each round to resist this effect.
Shadow of Death (Su)
Once every 1d6 rounds, Wormwood can extend its shadow as a standard action. Its shadow becomes as black as the void, except for two red glowing eyes, and covers a 120-ft. cone.
Those falling under the shadow take 25d6 cold damage. A DC 25 Fortitude save reduces this damage by half. Undead are not healed by this negative energy. The shadow is a necromancy death effect.
In addition, any creature who fails the initial save must make an additional DC 25 Fortitude save or have the water in its body turn into a deadly poison.
Wormwood can survive in the void of outer space. It flies through space at incredible speeds. Although exact travel times vary, a trip within a single solar system normally takes 3d20 hours, while a trip beyond normally takes 3d20 days (or more, at the GM’s discretion)— provided Wormwood knows the way to its destination.
Environment any vacuum
Wormwood is an enormous creature with eyes that glow with the light of dying stars, scales like polished obsidian tombstones, and a shadow that appears to twist and writhe with a life of its own.
Wormwood is the most powerful of the star beasts. Its presence alone is enough to turn the element most necessary for life— water—into a deadly poison. Wormwood is haughty and sees all but the most powerful of creatures as no more than insects and vermin to be destroyed if they bother it. Its hoard is hidden within the decrepit, long-abandoned capital city of a dead world.
Wormwood is 120 ft. long and weighs 24,000 lb. Wormwood prefers to lair where death reigns supreme. The ruins of once-great civilizations, the remains of shattered planets, and hollowed-out hulks of spacecraft have all served as lairs at one time or another.
