Ectoplasmator

An ectoplasmator was a reward from the 2012 Hallowe'en Event. It could be bought for 50 ectoplasm while wearing a full set of hallowed robes (from Brother Righteous) or unhallowed robes (from Brother Heinous), requiring at least 4 rounds where all 5 ghosts are found. It can be stored in Toy box in POH. It was also available as a drop from the ghosts in the 2014 Halloween event, Death's Door. Alternatively, it can be acquired as a rare drop from a number of ghosts during and after the event.

While it remains within a player's inventory or worn in the pocket slot, the ectoplasmator will give Prayer experience after killing most ghosts, similar to the bonecrusher. However, the ectoplasmator does not work with the Dungeoneering prayer necklaces (the twisted bird skull, split dragontooth, and demon horn necklaces) in restoring prayer points. For this effect, you will need to upgrade the ectoplasmator into an attuned ectoplasmator by using 100 ghostly essence on it.

Dropping monsters

 * An effective way of obtaining one is using a dwarf multicannon at aberrant spectres in Pollnivneach Slayer Dungeon, due to the high kill rate. Another effective method is using multi-target abilities and/or spells at banshee in the Slayer Tower. Utilising a spiritual combatant slayer task is a slower method but allows use of a slayer helmet's buff and gives slayer experience (and often greater profit from other drops).

Trivia

 * Its previous examine text was "An advanced piece of ghost-busting equipment.", which made a reference to the Ghostbusters franchise.
 * The ectoplasmator was made equipable in the pocket slot on 4 August 2014.
