So many Special Fighter ideas... looks like someone's niche is gone...

Sorry Legendary Ike but you just lost your unique niche.

Anyone holding a Slaying Weapon, DC, and Special Fighter and the QR seal can now proc an Aether in one round without relying on being doubled. This is great on high speed armored units. At least they got redeemed as they used to be outclassed by minmaxed, slow armored units. Amelia, Winter Robin, Draug, and even a Spd boon Winter Lissa can take advantage of this.

Not really gamebreaking but something nice to consider.
