Some servers now have the option to upgrade mods to give them secondary effects in combat. The types of upgrades available depend on the shape of the mod. Upgrading a mod requires new mod upgrade pieces.
Once a mod reaches level 30, you now have 3 different upgrades you can pick. Collect 15 mod upgrade pieces for the upgrade that you want and then use them to upgrade the mod.
Once a mod reaches level 40, it can be upgraded again by spending 40 more mod upgrade pieces of the same type. Each mod can have only one type of upgrade.
The shape of the mod determines which 3 upgrades a mod can potentially have. The color of the mod doesn’t affect upgrades.
Earning Mod Upgrade Pieces
Mod Upgrade Pieces can be earned from Invasion, starting the week after the 1.11 update (July 15). Only 3 types of Mod Upgrade Pieces will be available in Invasion to start: Armor, Purple Skill Levels, and Normal Crit. Only one type will be available each week. The other types will be coming soon.
