This is just a build I'm currently running with through NG (yeah) with great ease. Hopefully Hexes aren't the next big thing FROM decides to nerf.
Drangleic Sword +5 or your preferred GS
Dragonrider Bow (pulling/sniping)
Dark Black Witch's Staff +10
Pyromancy Flame +10 (Fashion Souls, looks cool with Alva set)
Drangleic Shield (Fashion Souls, I rather roll away from danger than try to block it)
Dark Mask +5 (not even Fashion Souls)
Alva Armor +10
Alva Gauntlets +10
Alva Leggings +10
Ring of Restoration
Ring of Blades
Ring of Life Protection (!)
(Greater?) Resonant Soul
Fireball (replace if you aren't playing Fashion Souls)
Not the most optimal build out there but this exists if not only to carry you through NG with ease, you can optimize it later. Use melee on basic mobs and spells only when situation requires and on bosses (co-op?). Roll away from danger. Stats don't exactly match SL150, I adjusted Strength a little to reach GS requirements. Use Royal Soldier's Ring if you plan to use GS.
