Fastest most effective build for tearing up 4 Kings all the way up to NG+7 difficulty. Power Within lasts the entire fight with Lingering Dragoncrest ring, and it won't take as much HP either. CMW lasts longer, but you usually need 2 casts of it for the fight. CHSM for little bit extra damage as you wait for new Kings to spawn. Extremely high magic resist gear so you don't take too much damage from the boss.
Perfect for Co Op in New Londo Ruins. Hornet rapier Darkwraiths on your way to boss.
