The ferox no longer only takes two element, you will now have to use more element to tame the ferox so make sure to bring a lot extra. (Ferox stats and levels are bugged so as of now it is not worth the element)
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. Please if this was helpful take it to the top.
