Aberrant spectre

Aberrant spectres are Slayer monsters that require level 60 Slayer to kill. They frequently drop large amounts of high level herbs and herb seeds. Due to the small distance from a bank (when killing them at the Slayer Tower) and their drops, killing Aberrant spectres is a great way of making money. A Macaw Summoning familiar is helpful as they will improve herb drops (requires level 41 Summoning).

Locations

 * Morytania Slayer Tower
 * Desert Slayer Dungeon

Strengths and weaknesses
Players must equip either a nose peg or a slayer helmet when fighting Aberrant spectres, or the player's stats (including hitpoints) will be rapidly reduced due to the Aberrant spectre's smell. Spectres use a very accurate Magic-based attack with a max hit of 11, which will hit fairly often even against a magic defence of +125 (Karils skirt, Karils body, mind shield, Barrows gloves, God Cape). Recommended armour is: dragonhide (preferably black) or Karil's; an elemental shield, mind shield or Holy book, with other high magic defence armour. The most effective way to kill them is to wear prayer enhancing gear and use the Protect from Magic prayer. During a trip they should drop enough Ranarr weeds to recoup or even make a profit over the prayer potions used.

They seem to be weak to Ranged attacks (although an Abyssal whip works just fine). In addition, if using melee, using a Salve amulet (e) will give a large advantage, since they are classified as undead. Despite their spectral nature, it is possible to poison aberrant specters.

The only non-aggressive Aberrant Spectres are in the Desert Slayer Dungeon. Players cannot kill them safely until the player makes the slayer helmet, because both the nose peg and facemask are needed to fight them without suffering the effects of the spectres or the smoke. The smoke, however, will only damage players down to 1 hitpoint, so it is possible to use a nose peg, with the Protect from magic prayer, to avoid damage from the spectres and remain at 1 hitpoint. This is very risky, as if the player's prayer runs out, or is otherwise turned off, for just a second, there is a very high chance that the player will die, and hence is not recommended.
