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
Repair Item Durability
The cost of repairing an item's durability is based on a few factors:
- T = Item Type Factor
- R = Item Rarity Factor
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
Repair Cost (C) = (B / 20 + 100 * B / 80) / 8
- Example: Repair Uncommon Armor
- B = 2^4 * 5 * 110 = 8800
- C = (8800 / 20 + 100 * 8800 / 80) = (100 * 8800 / 80 ) / 8 = 1,430
