Bucket of slime

Bucket of slime is a slimy green glowing liquid, found in an underground basement near  Port Phasmatys. Necrovarus  uses this liquid to control the ghosts of Port Phasmatys, but he is thwarted by the player during  Ahoy Ghosts Ahoy. It apparently has hidden magical properties regarding ghosts and the undead, which is the reason Necrovarus can control the ghosts of Phasmatys and also why he, along with his disciples, are still able to interact with living beings, even after many years of death.

It is used along with bonemeal or Demonic ashes to worship the Ectofuntus for training Prayer. If bones are ground and used with ectoplasm to worship the Ectofuntus, four times the normal amount of experience for the bones is given; which makes it a useful item that greatly impacts and cheapens training Prayer.

Obtaining Ectoplasm
Ectoplasm can be obtained by useing a empty bucket on the pool of slime underneath the Ectofuntus

Trivia

 * The ghosts that inhabit Port Phasmatys are actually made of ectoplasm, as are mythical and real-life "spirits".
 * With the release of the Charter ship, the sailors sell players buckets of slime.
