Windherder Enchantment Idea List. Confirmed possibilities are marked, everything else is speculative.
Grey+Gold:
Eye of the Beholder(RS)+Fool's Gold (MC): Target object is actually irresistibly valuable now. - Shard
Shadow Knives(FC) +Silver Arrows (MC): Enchant a crossbow to fire armour-piercing homing bolts.
Bewilder (RS) + Guard of Steel (RS) = Bronze Orbs that in addition to protecting you, also seriously disorient anyone hostile to you. Constantly. -Shard
Stoke the Forge + Burning Shadows = Target Fires burns hotly with a Burning Shadows effect. Very lethal. - Shard
Aethyric Armour + Guard of Steel = Two seperate defensive effects that can be used together. - Jyn Ryvia -
Confirmed
Marksdwarf pistol from Zhufbar + Illusion(FC) + Enchant Item(FC): Silenced supergun -Picklepikkl
Grey+Jade
Shadowsteed (RS) + The Wild's Undisturbed (MC): Creates a shadowsteed leaves no trail and passes through wilderness
Shadowsteed (RS) + Tree-dweller's Step (RS) = Shadowsteed that can climb? - Shard
Take No Heed/Shroud of Invisibility/Shadowcloak + The Wilds Undisturbed (MC) = Super Sneak through forests - Shard
Grey+Celestial
Illusion(FC) + Polish-Clean-And-Gleam(RS): A self-cleaning silenced rifle - Klaus
Aethyric Armour + Wings of Heaven (MC): Robes of flight - Jyn Ryvia -
Confirmed possible but inadvisable
Grey+Bright:
Bewilder(RS)+Choleric(RS): Target becomes confused, with the only clarity being their anger at one target.
Shadow Daggers(FC) + Fireball (MC) - Shadow Daggers that explode when they hit. -
Confirmed
Grey+Amber
Dread Aspect(FC) + The Ox Stands (MC): Makes the user utterly terrifying, but makes their allies immune to terror.
3-mage projects: Using two winds that aren't Ulgu requires three mages, one per wind+mathilde, and is thus automatically more dangerous
Bright+Jade
Barrel of Ferment(RS)+Taste of Fire(RS) - Converts any liquid, no matter how foul or brackish, into strong booze- Businessmanga
Amethyst+Jade
Death's Door(FC) + Seed of Regrowth(Battle): This would theoretically solve the problem of our opponent being able to stop us from regenerating after they kill us, by allowing us to keep fighting while we heal. - Klaus -
Confirmed to be attemptable
Light+Gold
Inspiration(MC) + Law of Logic(RS): An initial boost of creativity and then Law of Logic to allow them to develop the concept to fruition. -Alratan
Things we definitely can't do:
Combine Aethyric Armour with anything that makes armour stronger.
Combine Mindhole with effects of other winds to change its targeting.
