Not 100% accurate to Solaire's character but I wanted to make it a bit more viable for PvP. Buff the +15 Sunlight Straightsword with Sunlight Blade, and when that runs out switch over to the +10 Divine Sunlight Straightsword. You can use this build to invade or to fight invaders, if you feel like staying true to the Warriors of Sunlight and being a gold phantom.
