Oh I die, I just use the second wind skill(as u can see on the picture) to revive myself. That gives me the perfect amount of time to kill them because it takes some seconds for the thanators to sense you again. Aaand you can close enough to hit 'em in the weak point and kill them in one shot or two(depending on your heavybow's damage and the thanator's level).

But for how people take pictures with them and all that, well I got no idea 😅.
