Roost gives a bonus to falconer skills (+50% damage), maybe it doesn’t sound like much, but trust me, it actually makes a lot of difference, especially when you use kneeling shot with pheasant or sonic strike
As mentioned it adds +50% more Falconer dmging skills. That with the new insane Pheasant skill dmg post rework + Kneeling shot is insane.
Also I forgot to mention, I am a full dex build. So while I do all the Roost+Pheasant+Kneeling combo, with Monstrance I get a lot more DEX. And kneeling shot is calculated based on DEX. So everything works out perfectly like this for me…
