I just spent the last 3 hours trying to tame this thing, and after taming it, it's really not worth it.

The feathers are cool and all, but they're only usable on big slow targets, mine was a 135 base tame, and it's damage is around 1,200 damage with a full rupture, but it takes so long to do that it can't really kill anything. Making it really difficult to level.

Maybe after some decent leveling it'll be better than the dire bears I've got, but for now it's pretty much just a trophy creature.
