Recombinator

A screenshot of the recombinator interface.

The Recombinator is a crafting device that lets you combine two magic or rare weapons, armour, or jewellery of the same item class into a new item. It can be accessed via Gwennen, Rog, or Tujen. It is unlocked after completing your first Expedition, and requires artifacts found during the Expedition to fuel it.

Mechanics

Players can input two items and select one or more modifiers from both items to be retained on the output item, with an overall chance of success displayed on the interface. A modifier's contribution to chance of success is explained below. Additionally, as more modifiers are selected, the chance of success decreases. If the craft fails, both input items will be destroyed without creating an output item.

Each attempt at the recombinator requires Expedition artifacts. The Expedition artifact cost of the recombination depends on the category of item being recombinated, as well as the item levels of the input items:

• Weapons: Broken Circle Artifact
• Armours: Order Artifact
• Jewellery: Black Scythe Artifact

The recombination animation can be skipped by closing the menu; if the item succeeds, the input item chosen as the base type for the output item will remain visible in your inventory greyed out until the animation finishes. If the craft fails, both input items are immediately removed from your inventory.

• The output item will be chosen from one of the input items; the chance for either base type to be chosen is based on the relative success chance of either chosen modifier. The logic for 3+ chosen modifiers is currently unknown.
• The item level is the item level of the chosen base. If the selected input item has enchantments or sockets, this will be retained on the output item.
• The resulting item will always be rare even if the resulting item only has one prefix and one suffix.

Restrictions

• The input items must be magic or rare.
• The input items cannot be Corrupted or mirrored.
• If both input items have a modifier of the same mod group (e.g. any +# to Strength modifier shares the "Strength" mod group), only one can be selected.
• If three total prefixes or suffixes are selected from either input item, no more prefixes or suffixes can be selected.
  • This may be bypassable with certain base types such as Penumbra Ring
• Fractured modifiers cannot be selected. However, fractured items can still be used as an input item. Additionally, if the chosen base had a fractured modifier, that fracture will be retained after recombination even though the player did not select the fractured modifier. The extra fractured modifier does not cost extra artifacts and does not decrease the chance of a successful recombination.
• Modifiers that cannot exist on the opposite input item's base type (e.g. energy shield modifiers on a pure armour base type, modifiers with a higher level requirement than the base type's item level) cannot be transferred; the chance for success automatically calculates this.

Determining success chance

An individual base's chance of success is determined by the following formula:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}SuccessChance={\frac {a*(weight_{Mod}+weightsum_{HigherRollableTiers})}{weightsum_{AllMods}}}$

where:

• $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}a$ = the base type coefficient, listed below.
• $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}weight_{Mod}$ = the chosen modifier's weight.
• $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}weightsum_{HigherRollableTiers}$ = the total weight of all higher tier versions of the chosen modifier that are rollable at the base type's item level.
• $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}weightsum_{AllMods}$ = the total weight of all modifiers that are rollable at the base type's item level.

In simpler terms, higher tier modifiers have a lower chance of success, and higher item level base types dilute the modifier weight pool to lower the chance of success unless the item level is high enough to unlock a new tier of the chosen modifier.

For example, a spear with chosen "Tyrannical" (155-169)% increased Physical Damage (Level 73) will gain a lower chance of success from ilvl 73-81, but at ilvl 82 the chance for success for Tyrannical also includes the weight of the next tier "Merciless" (170-179)% increased Physical Damage (Level 82), almost doubling the success chance.

The actual success chance of the craft for 2 chosen modifiers is the sum of both base types' success chance. The success chance formula for 3+ chosen modifiers is currently unknown.
