Fenumal Plagued Arachnid, also known as FPA or split beast, is a type of beast that can be used to "split" rare items into two. It always appears and captures as a red beast and as a rare monster. Using this beast on items is typically called "beast splitting" an item.

can also be used to split an item. It has the same restrictions as the split beast.

Monster skills

The monster summons Fenumal Pus Arachnid and Fenumal Virulent Arachnid.


Using a Fenumal Plagued Arachnid to split an item will result in the Split tag being added to both items, preventing them from being split further. Aside from this restriction, Split items can be crafted normally.

Beastcrafting Recipe: Split an Item Into Two, With Half the Mods on Each Item


  • Splitting a rare item into two can turn one or both copies into a magic item depending on the remaining mod count. The resulting items keep the quality, number of sockets, colour of the sockets and socket links of the original item.
  • Does not work on influenced items, fractured items, synthesised items, unique items, mirrored items, corrupted items (including Breach RingBreach RingProperties are doubled while in a BreachCorrupted, Talismans, etc), items with catalyst quality, or items with enchantments, and items with the Split modifier.
  • Items with legacy implicit mod can be used.
    • For example, certain basetypes that have the implicit mod replaced, such as Assassin BowAssassin BowBow
      Physical Damage: 43-130
      Critical Strike Chance: 6.70%
      Attacks per Second: 1.25

      Weapon Range: 1.3 metres
      Requires Level 27, 45 Str, 54 Dex+185 to Accuracy Rating
      , etc. can be used.

    cannot be used to revert a Split modifier item to a state without the Split tag. An item that has the Split tag can still be imprinted and restored to a state after gaining the Split tag.
    • Split beasts were previously used to duplicate copies of items with Incursion mods, Delve mods, Warband mods, or legacy explicit mods (non-influenced only) that are now difficult or impossible to obtain, as imprints used to work on one of the split copies, sometimes referred to as a "master" copy, providing a 50% chance to continue duplicating new bases. After the changes in version 3.14.0 to how the split items work and the introduction of the Split tag, it is no longer possible to make infinite copies of these items as split bases cannot be restored to their "master copy".
  • For split Blueprints (an item for opening a portal to a grand heist), the layout and reward icons of the grand heist is not affected. The rooms only need to be revealed again by spending Rogue MarkersRogue's MarkerStack Size: 50000Creates a portal to the Rogue Harbour from a Town or Hideout

    . However, since version 3.14.0, blueprints can only be split once instead of many times, thus the beastcrafting recipe now merely doubles the number of the good layout blueprints.

Item acquisition

According to a datamined list, the minimum Map level required to capture a Fenumal Plagued Arachnid was map Level 70 (during Bestiary league).[1]

Since this beast is from The Caverns family, the chance of spawning this beast could be boosted by Fenumal LureFenumal LureArea contains Einhar
Area contains 4 additional Red Beasts from The Caverns
Cannot be used alongside a Bestiary Scarab
Can be used in a personal Map Device to add modifiers to a Map.
, but lures no longer drop after 3.19. Alternatively, atlas passive skill The Hunt for Fenumus can boost the chance to acquire beasts from The Caverns family.


In Bestiary, the classification of Fenumal Plagued Arachnid is as follows:

  • Genus: Spiders
  • Group: Arachnids
  • Family: The Caverns

The beast is placed in the cage named "Disease-bearing arachnids" in the Menagerie Caverns, along with Plagued Arachnid and Diseased Arachnid. The latter is not capturable anymore.


Version history

Version Changes
