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.
Get owl, burn it’s stam by freezing, it’ll give you pellets, drop pellets on ground for Gacha. Tamed a 130 in a minute on x3. Super easy. Also got a green riot chest piece and yellow fab sniper from sparkly crystals wild ones drop so there’s that lol
With a baby gacha, it is best to use meat in the beginning. Berries are Not the right food, as it allows for their food health to go down too quickly which in turn allows for them to starve to death. Meat is best and then as they gain weight, both stone and meat can be used.
The best way by far is to just use load of stone and try to keep it eating a all times. I tried stone structure for a level 145 and I made 36 structures and it only went up 7 percent. I used a ton of stone for the same gacha and it tamed in under 5 minutes (don't drop them one by one)
