Genshin Impact has been one of the best and biggest surprises of 2020. It's an exceptional free-to-play gacha game that walks and talks like a big-budget JRPG, but it still has some frustrations. Chief among them, for many players, is the Resin system, which effectively gates how often players can get rewards from certain activities like killing special bosses or completing dungeons. Each time you beat one of these fights, you have to spend some Resin to actually access the loot, and it regenerates painfully slowly.
