They are safe just feed it and you’ll tame it no need for Tranks just be carful because of the wasted land so bring creature pods (if you have them) to put them in or hope they don’t die on the way to your base
If your gacha can make congealed gas balls I’d do it because it’s faster than waiting 10 hours for you to get the concealed gas to make crafted gasoline or elements on aberration heads up you cannot find a gacha normally on aberration you need to spawn it in With commands
Gachas throw temper-tantrums when not mate boosted. So remember if you want to farm them keep them far apart from same sex gachas and each should have their own mate. Ex. 2 f and 1 m can make them get jealous with purple lights and vise versa.(they will refuse to take anything and won't produce anything.
Make sure when you drop items you drop them from YOR inventory, DO NO drop them from your mount or you will WASTE your items. I learned this after I drop 100 stone walls from my tame to a lvl 150 and then I hopped off and threw down 90 more and it was only 45%tamed. So I wasted 100 stone walls.
The Gacha cannot be carried by any Extinction flyer. They also require being spread out about 12 foundations apart IF they’re the same gender. Breeding pairs are okay. You must manually turn their resource collection ON after taming; it is off by default. They eat meat as babies and all levels should be placed in Crafting Skill. Also, take a look at their production tab! Each gacha has a custom loot pool and you can choose specific resources for it to drop, which will NOT impact your chances of getting items.
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.
