Really good tame for early game. When you tamed it, all you have to do is force feed him stimberrys, he will sit down for about 30 seconds. Then he will poop a crystal, which you can eat and get some decent loot (fungal wood, sap, flak, riot, crossbow...) I've been farming for one hour and i got a full mythic riot set
Gachas are essentially living lootboxes and resource farms. They will eat anything (including stone, wood, or fiber) and turb it into crystals which can drop a variety of resources including black Pearl's, organic polymer, or obsidian, among other things. They also have a rare chance to drop higher-tier crystals which turn into upgraded armor and tools
In order to get the tamed Gatcha to drop loot crystals make sure you have owl pellets and stone in its inventory. 1 owl pellet + 20 stone per loot crystal. If you have tamed snow owls just park them near the gatcha and the gatcha will pick up the pellets automatically.
