Abyssal lurker

An Abyssal Lurker is a summonable familiar released with introduction of the Summoning skill. It requires level 62 Summoning.

Abyssal lurkers are classified as Beasts of burden because they have 7 slots for unnoted rune essence or Pure essence. As they are also Abyssal creatures, they are one of only three familiars able to hold essence. The other two familiars with this ability are Abyssal parasite and Abyssal titan.

Abyssal lurker pouch
An Abyssal lurker pouch is made by using a Summoning pouch on a Summoning obelisk with 119 Spirit shards, a Green charm and an Abyssal charm in the player's inventory.

Abyssal stealth scroll


The Abyssal stealth scroll enables the use of the Abyssal stealth special ability for an Abyssal lurker. Using an Abyssal lurker pouch on a Summoning obelisk creates ten Abyssal stealth scrolls.

Abyssal stealth
Abyssal stealth is an effect generated via the Abyssal stealth scroll. In order to create this effect, you must first have summoned an Abyssal lurker.

The Abyssal stealth effect temporarily increases a player's Agility and Thieving by 4 levels. This is the highest boost for thieving aside from using a spicy stew. The Agility boost from the abyssal stealth scroll does NOT stack with that of an Agility potion.

Abyssal Stealth is part of the Summoning skill and as such grants 0.1 Summoning experience when the scroll is created and another 1.9 Summoning experience when the scroll is activated.
