Please note the like megalanias,wild griffins are aggressive and get attacked by other carnivores,and does zero damage,so u won't hav to worry if a therizinosaurus kills it while taming it.(edit:zero damage to wild creatures)
On mobile you have to either
a)be level 85+-95+ depending on difficulty
b) buy the crown which requires the primal pass and 100+ amber
c) have your name end with a surten syllable (look on yt/Google for the options) and be level 40+
If you don't do that then the Griffin won't eat when unconscious.
Sorry for th long tip.
The speed demons of the skies.if you meet one i hope your on a fast moving tame as they'll tear you a brand new one otherwise.even with the flyer nerf a high level one can outrun a wyvern without trying.
Most amazing thing ever I was in the Wyvern cave with my griffin and I get knocked out by a Lightning Wyvern and fall into the water and barely escape I come back 2-3 days later and I find this guy wandering around looking for me I brought him/her (gender is n/a) back to base and renamed it mr.loyal (don’t judge me)
