This build is centered around using the moonlight greatsword, and sorceries. This is an excellent build if you prefer sorcery to miracles, hexes, or pyromancies.
With this build your main damage will be from your spells and secondary damage from your Moonlight Greatsword.
The recommended spells will be:
Great Heavy Soul Arrow X2
Homing Crystal Soul mass X2
Soul Spear X2
Soul Geyser X1 (for PvE use due to slow cast speed)
