even post patch, going with divine isn't worth it. If you had to, I'd say go with occult, though fire and lightning is much MUCH better anyways. As for weapon, like +Tim Morgan
& +Joseph Tomkins
said, it all depends on your style. But it'll help if you "master" a weapon with range, like spears or even the great weapons, & also "master" fast weapons such as a katana or a dagger. As for me, I stick with the uchi + lightning because of the damage output and because of its bleed property. My one and only character nowadays is a sl 50 faith build so believe me when I say that this is the best build I could come up with, for my style at least. Oh and I invade so I'm always expecting a 3 on 1 match.
