Perk Recombobulator

The Perk Recombobulator is a feature Fortnite: Save the World that introduced more ways to upgrade the perk loadout for weapons and traps. It was introduced in Update v4.20. The Perk Recombobulator is unlocked when you complete:
 * Plankerton Storm Shield Defense 2.
 * 2 Perk Recombobulator Side-Quests.

Modify Perks
To access the Perk Recombobulator, goto the upgrade screen and choose "Modify Perks".

RE-PERK & PERK-UP
Replacing or Upgrading perks costs two new resources:
 * RE-PERK! & PERK-UP!, respectively.

RE-PERK! is available throughout all mission difficulty zones such as Plankerton. PERK-UP! begins appearing at the same time as RE-PERK, but also has different rarity levels; the rarer versions become available as players progress through higher and higher mission difficulties.

Rarer PERK-UPS wil appear in mission rewards, mission alert rewards, and repeatable quests.

In addition, you’ll be able to choose which element you want on your weapon. This modification requires elemental resources named FIRE-UP!, AMP-UP!, and FROST-UP! You can find these resources in mission alert rewards and repeatable quests.

Legacies
Modifying and converting a legacy weapon or trap with the Perk Recombobulator will remove it's original perks and cannot be reverted.
 * Legacies will be changed from 5 perks to 6 granting a "Free Slot".

Perk Slots

 * Elemental items now have a dedicated perk slot.
 * Perks have five levels of power; (Common, Uncommon, Rare, Epic, Legendary)
 * If you want your Legacy item to reach its full potential, you’ll have to convert it using the Perk Recombobulator.
 * Each perk slot has a range of possible perk types that it can contain. Players can choose to replace a perk in a given slot, but the list of perks that a slot can be changed to is limited in scope, and varies from slot to slot. Some perks cannot be changed at all.
