This has been my recent build for anonymous co-op play. I think the gold(ish) color scheme is a great fashion souls touch to what's essentially a carebear sunbro.
None of the armor needs a slab to get to it's best stats (a plus for strictly fun builds) and it has the poise and defense to not be a liability at any stage of the game. The choice of the jagged ghost blade allows me to always be useful without ever needing to worry about being so strong that the summoner isn't doing anything. I'd get better damage using a fire composite bow and fire arrows, but I like having access to both elemental attack types without needing to change what weapons are equipped.
