Players can Upgrade their schematics to improve the Power Level. Schematics may be added to the Collection Book or Recycled. Increases in rarity of the schematic typically increases damage by 8%-15%. As a general rule, a legendary schematic will have roughly 1.5 times more base damage than a common schematic. Each level of the schematic adds 5% of the average damage of the 10 levels of the prior evolution tier (for common rarity schematics, this will be 5% of the base damage). Evolving a schematic to the next tier will increase damage by 20%.
Each level of rarity above uncommon adds 50 to the base experience points required for the next level. Base experience starts at 150 for uncommon schematics. The next schematic level costs base level experience * current schematic level. So leveling a rare from 15 to 16 will cost 3,000 schematic experience (200 base for rare * 15 levels).
Certain Schematics can be obtained through daily reward coins and event currency, and can be accessed through the "Item Shop" tab and then choosing the sub tab of "Event" and there are 2 sections divided into "Event Items" and "Weekly Items" Schematics can also be recycled. Every time there is an event you can get different seasonal schematics
