Fenumal Plagued Arachnid 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.

Beastcrafting Recipe: Split an Item Into Two, With Half the Mods on Each Item
Since version 3.14.0, beast splitting an item adds the "Split" tag to both items (similar to "Mirrored" tag), which prevents the items from being split or fractured again. Split items cannot be split again, and cannot have Imprints made of them or applied to them. However the item can still be mirrored using a Mirror of KalandraMirror of KalandraStack Size: 10Creates a mirrored copy of an itemRight click this item then left click an equipable non-unique item to apply it. Mirrored copies cannot be modified. Shift click to unstack..
Mechanics
Splitting a rare item into two can turn one or both copies into a magic item depending on the remaining mod count. Both items would keep the number of sockets, colour of the sockets and sockets links.
Since version 3.14.0, splitted item can not be split again, but before that, using this beastcrafting recipe is a profitable way to sell the copy to the market by preparing a good base item by 6L, 30% quality and 6 white socket it, and then split the item. After the aforementioned patch, the profitability depends on the price of the Fenumal Plagued Arachnid beast and the price of such splitted basetype that have Split modifier as a "contamination" (Read below for the drawback caused by the Split modifier)
Splitting an item will maintain the item level of the original item
Does not work on influenced items, fractured item, synthesised item, unique item, MirroredMirror of KalandraStack Size: 10Creates a mirrored copy of an itemRight click this item then left click an equipable non-unique item to apply it.

Shaper/Elder-influenced Stygian ViseStygian ViseHas 1 Abyssal Socket is one of few basetype that cannot be duplicated for example.
For example, certain basetypes that have the implicit mod replaced, such as Assassin BowAssassin BowBow Physical Damage: 30–89 Critical Strike Chance: 6.70% Attacks per Second: 1.25 Weapon Range: 120Requires Level 62, 212 Dex+(15-25)% to Global Critical Strike Multiplier, Ornate SwordOrnate SwordTwo Hand Sword Physical Damage: 30–50 Critical Strike Chance: 5.00% Attacks per Second: 1.40 Weapon Range: 13Requires Level 27, 45 Str, 54 Dex+185 to Accuracy Rating, etc.

This imprint can later be used to restore this specific item to that imprinted state. Shift click to unstack. cannot be used on the Split item, including the "master" item, as the beastcrafting recipe will add Split modifier to both items.
Thus, despite the beastcrafting recipe works with Incursion mod, Delve mod (both fossil craft or drop only) Warband mod or legacy explicit mod (non-influenced only), etc, such mod cannot be restored on the "master" item via Imprint since version 3.14.0, effectively ending the method to duplicate the modifier. The beastcrafting was used to be use along with Imprint as there was 50% chance a desired mod was transferred to the copy, thus player can use Imprint on the "master" item to restore the mod(s), effectively duplicate the basetype and the explicit mod.
For Blueprint (an item for opening a portal to a grand heist), except the explicit mods are distributed by random to the "master" item and the "copy", the pattern of the rooms of the grand heist is not affected.
