Overclock

Overclocking is the games prestige system that allows you to reset your level back to 1 from 100 with an upgrade from the shop. Each time you Overclock, you gain increasing Experience by 15% up to a cap of five upgrades for a total of 75% bonus EXP, and increasing HP by 50 up to a cap of ten upgrades for a total of 500 bonus HP. Past that, the level cap for Overclocking is Overclock 110. Reaching your first Overclock will also unlock in-game features such as trading, gifting and the Marketplace. Overclocking after OC 100 requires an Overclock Lv100+ coupon from the shop.

You can Overclock further to access more powerful items in the Overclock shop, including powerful Mercenaries and Transformation Packs as well as quality-of-life items such as long-term Skill Packs, discounted Consumables and upgrades that automatically sell the more common items as you find them. Overclocked players can wear items without level restrictions and can go back and level through all of the early and midgame maps, like a New Game+.

You can also increase your Overclock with an Overclock++ coupon, an incredibly rare item that can be found in any Sector map. Use Overclock++ to gain another Overclock but keep your level 100.
