Throne and Liberty Gear Upgrades
Upgrades can sometimes increase the performance of a piece of equipment and, sometimes, even add extras. The value of these upgrades is determined by their tiers, requirements and the amount of random augmentations used.
The elite racial Shield Razortail, for example, is frequently upgraded to enhance its lightning absorption function in PvP, and/or to add additional defenses to missile-based builds in the PvM. This makes it more tradable over the original version that is not upgraded.
Reroll Tokens
Reroll tokens are a way to reroll an item upgrader kit you have acquired, such as an armor, weapon or rings. The Best item upgrader item upgrade upgrade items (More Help) is replaced by an identical item upgrader mod, but with different benefits. Reroll tokens are an efficient method of upgrading equipment. They don't keep the original equipment's condition and any money wasted won't get compensated.
Survivors can obtain Reroll tokens in a variety of ways, including the Mistery Box and rare drops from skulled creatures.
