Aberrant Specters are one of the oldest monsters in Old School Runescape. They are a slayer monster that requires the player to have level 60 Slayer to kill. These monsters don’t have a particularly unique drop but they are important for Ironman players as they drop all sorts of herbs and seeds. Let’s take a look at where these monsters can be found, their weakness, and what to use against them.

Best Places to Kill

There are 3 locations in total where you can find these monsters.

Slayer Tower 1st Floor

This is the original location that these monsters reside in. This spot is usually not preferred by most players as it is harder to get to compared to the other locations. The main benefit of using this tower comes from its safe spots. There are 3 locations you can use to lure and safely kill these specters with a crossbow. For a normal account, this is not that important but for Ironman who needs to conserve their supplies, this can be crucial. Here are the safespots that you can use in this tower against these monsters:

Stronghold Slayer Cave

This is the most preferred spot that players usually go to for a couple of reasons:

1. This spot allows you to utilize your cannon for faster kills.
2. It is close to a teleport and a bank.
3. There are also 4 safe spots that Ironman can take advantage of.

Here are the safe spots you can use in this cave:

Catacombs of Kourend

This spot houses the more difficult versions of this creature called Deviant Spectre. Their stats are better than their normal variants. There are a few reasons why you might want to choose this variant and location instead of the others:

1. You can get more Slayer experience from each kill. Aberrant Spectres give 90 Slayer XP per kill whereas Deviants give 194.5 XP.
2. There are also 2 safe spots that you can use.
3. Since we are in the catacombs, we can get totem pieces as well as ancient shards.

Here are the two locations you can use for safe spots:

Weakness & Strategy

Aberrant Spectres

Regular variants are pretty much weak against everything, but since they use Magic-based attacks and attack from a distance, it is recommended to use the Ranged style as it will speed up combat.

The best way to hunt these monsters, if you have a regular account, is to use the Gnome Stronghold Slayer Cave. Bring along your best-ranged gear alongside a toxic blowpipe that uses amethyst darts. Make sure you have your dwarf multi-cannon as well. Find an empty spot, turn on Protect from Magic and auto-retaliate, set up your cannon, and AFK.

If you want to conserve supplies, bring your crossbow instead without a cannon and use the safe spots shown above. Any bolt from broad-bolt up is fine.

Deviant Spectres

Deviants have slightly higher resistances against all styles except Magic. Melee might be more optimal for these ones but Ranged is also great.

Since these creatures will take longer to kill compared to their regular counterparts, it is recommended to bring along your best prayer gear with your best melee weapon. Once again, turn on your auto-retaliate and Protect from Magic and enjoy your AFK time.

If you want to conserve supplies, bring your crossbow with some ranged gear instead and use the safe spots shown above.

Best Gear Setups

As mentioned above, you can use pretty much any style you want to hunt these spectres. We will provide some examples. Remember that it is a must to use a nose peg or a Slayer helmet. If you don’t, the spectres will absolutely shred through your character.
