Wait until it does the little “emote” before you feed element. This will ensure you won’t lose any ele during tame. Like so people can see

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.

Take a grapple and parachutes.
Hotbar the element, feed it then grapple to the roof before it turns all Bruce Banner on you.
Wait until it calms down then rinse and repeat.

The Ferox is a shoulder mount! Also, they run from attacks when they’re smol, but will quickly dig for element to help them.

Don't feed him element after midnight and don't let him get wet....wait a minute.
