Gear Material is used to level up gear. It is obtained by shattering gear pieces. Gear Material is required to level up a piece of gear. The amount gained by shattering a piece of gear is always the same as the level of the gear times 20 (e.g. a level 5 gear will yield 100 gear material), but the cost to level it grows exponentially, making it extremely costly at higher levels. It costs 264,900 Gear Material to max a piece of gear (increasing its level from 1 to 70), or 1,324,500 for all 5 pieces for a single hero. As of 1 May 2019 there are 88 heroes in the game, so maxing all their gears once would cost 116,556,000 Gear Material (more than 116 million).
