To escape: you can swim use a flyer use a raft or take your chances and run.

To tame: you can make it on a big rock with a ladder (what I did) or you can use stone but I'm not too sure about wood. Hopefully this helped.

PS: DONT LET IT IN WATER I killed my first one like that.

After you tame it upgrade its weight health melee damage movement speed and stamina as much as possible even by its self it can wipe out a group of raptors with its natural health and strength.
