A few gilding suggestions to give purpose to some unused bird materials.
Seagull Feather + Crab Claw = Scavenger's Bits
+2 Surv, +2 Masonry
A nice little early game curio, when for example you're boating around looking for both decent clay and water nodes.
Mallard Feather + Sand + Snow = Migrant's Memento
+2 Will, +2 Charisma
Channel the migratory powers of the duck as you travel back and forth along roads between questgivers.
Wood Grouse Feather + Bloody Mess = Bloodstained Feather
+2 Agility +3 Unarmed Combat
Two combat stats that haven't been combined until now for the fightingest of birds.
Golden Eagle Talon + Eagle Owl Eye = Clasped Oculus
+4 Perception, +4 Exploration, +4 Marksmanship
The visual acuity of the birds of prey feels right for both foraging and ranged combat.
It would also be cool if the Feather Band had some special interaction with Feather-based gildings. Maybe one or two guaranteed gildings when using feathery items, or all feathery gildings have an increased success chance?
