If your falling off a cliff just simply dismount and he won't rage up on you, good luck fellow survivors

WHEN TAMED! On a pvp server mostly make sure 100% of the time he/she is in a separate cage completely away from all other Dino's!! This is because after a certain amount of dmg done to the giga he will begin to "rage" he will turn on you even after all the happy memories you've had. Also even attacking all his Dino friends! :( so be sure to lock up this beast of a Dino!

Use a cryopod while raising. Just trust me.

It may seem easier to tame a low level, but believe me, the low levels have terrible stamina and melee. Tame the highest level you can.
