The Ominous Catalyst is an extremely mysterious item used to awaken the powerful Luxtructosaurus when thrown near a Volcanic Core. Unlike most other items, it is immune from being destroyed by fire and lava.



Ominous Catalysts are crafted from 8 Heavy Bones and an Amber Curiosity.

Ominous Catalyst



If an Ominous Catalyst is thrown in an cubic area spanning 20 blocks in all horizontal directions, 98 blocks up, or 8 blocks down from an active Volcanic Core, it will be pulled towards it in a straight path. Due to its straight pathing however, if a block obstructs the core's pull of the Ominous Catalyst, it will become stuck and unable to clear the obstruction.

If being within 1 block of the an active Volcanic Core, it will immediately despawn and summon the Luxtructosaurus - making a devastating battle ensue.

  • Strangely, Ominous Catalysts are held in your hands like how a sword would when viewed in third-person. Thus, the item is bigger in your hand and held vertically.
