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.
If you have access to a snow owl, you can tame these with any crossbow! Just shoot it until it looks bloody, and heal it with the snow owl’s ability. Do it so that it heals quite a bit, but not so long that the torpor drains back empty. Then hop off the owl and continue shooting it with tranq arrows. I knocked a 140 with a 279 crossbow and using this method it had over half hp remaining once it finally went down. Help this get to the top!
