For some reason the animation with 3 and 4 demon birds doesn't work for me, that is, 2 birds grab Hailey and that's it, the rest run away, I don't understand, maybe there are special conditions for these animations?
The boss have to be low hp, or you have to watch 1 bird, 2 bird animations first, i also ate a lot of meat from the birds and the 3 and 4 bird animations worked for me i don't know exacly what did it
