Go to extinction with a doedic, farm lights for dust. Transfer to genesis, convert dust to element. You only need to use one grapple hook. If in the cave. You can reel or far enough to never have to let go
As of 3/28/20. Ferox will tame at the wrong level but once put in cryopod will correct to tamed level. A live 145 changed to 217 once in pod post tame. Also dododex is not accurate on x3 possibly x1. The same 145 took 20 element for full tame. At 5% per element.
Best taming method is by getting a snow owl with 6k stamina and after you gave it element freeze it till u have no stamina and it will transform back to normal without big problems. Like so other can see
