Engineering Cost Algorithm

Upgrade Rarity

The cost of upgrading an item's rarity is based on a few factors:

  • T = Item Type Factor
  • R = Item Rarity Factor
  • D = Item Durability

Item Type Factor:

  • Weapon = 6
  • Armor = 5
  • Storage = 4
  • Engine = 10
  • Computer = 6
  • Harvester = 8
  • Special = 10

Item Rarity Factor:

  • Uncommon = 2
  • Rare = 3
  • Ultra-Rare = 4
  • Legendary = 5
  • Precursor = 6

Base Cost (B) = R^4 * T * 110

Upgrade Cost (C) = B / 25 + D * B / 90

  • Example: Rare Storage 50% --> Ultra-Rare Storage 50%
  • B = 3^4 * 4 * 110 = 35640
  • C = 35640 / 25 + 50 * 35640 / 90 = 1425 + 19800 = 21,225


Change Rank

The cost of changing an item's rank is based on a few factors:

  • T = Item Type Factor
  • R = Item Rarity Factor
  • D = Item Durability

Item Type Factor:

  • Weapon = 22
  • Armor = 18
  • Storage = 14

Item Rarity Factor:

  • Uncommon = 2
  • Rare = 3
  • Ultra-Rare = 4
  • Legendary = 5
  • Precursor = 6
  • Ultimate = 7

Base Cost (B) = R * T * 30

Change Rank Cost (C) = B / 25 + D * B / 90

  • Example: Legendary Weapon Rank IV 75% --> Legendary Weapon Rank V 75%
  • B = 5 * 22 * 30 = 3300
  • C = 3300 / 25 + 75 * 3300 / 90 = 132 + 2750 = 2,882
