USE COOKING POTS. Much less resources to use, and works almost as well as tek. Got a 130 last night in about 20 seconds on official during 2x. We used 5 separated stacks of 10 cooking pots, waited for it to sit the dropped each stack back to back. The Gacha will eat all the stacks in about 20 and be done with around 99 effectiveness.
Would highly recommend this meathod cause we tried using greenhouse stuff following the amount from dododex and that only got us to about 60%, then we were scrambling to make anything and just lost it from there. Cooking pot stacks was a suggestion from a person on our server and wanted to share here.
You can also follow a wild one around for a while and just collect its crystals before you tame it to see what it will produce. After taming several now, the crystals it produces when wild are always the same after they are tamed. GL
