Kachow what's popping true believers it's ya boi Lokus with another forum post
So, Firebird has an issue regarding two skills at the moment. Falcon Strike and Lift Off.
Lift Off's secondary effect of dropping feathers in the AoE does not proc properly. It will consume the five feathers but not give you the secondary effect. The same issue is with Falcon Strike. The feathers on the ground do not resonate when you have the required minimum of three feathers, but consumes the feathers as well. Falcon Strike's issue might be a bit more tricky, since you lose feathers when you move. But Lift Off is a bit easier to tackle (presumably) since it just consumes the five feathers without requiring that you move.
