Obedience

Effect
-0.8% Tame Health Level Modifier (effect increases with skill)

Obedience
I think level 40 is good for this as this will determine at what level you pet will flee if his health gets too low. At level it is 30%, at level 60 it is 45%, 80 it is 60%, at 100 it is 75%. I did not see a big difference. Just keep healing your pet and he won't flee.
