Notes from author
My Gravelord Servant build. Focuses on offensive miracles/pyromancies with moderate survivability.
If desired, move some points out of VIT and into DEX for faster casting and a little more damage from the Gravelord Sword. Points can also be moved out of END, but depending on desired roll speed you may have to wear the full Gold-Hemmed Black set instead of using the Black Iron chest piece. You can do this anyway if you are willing to sacrifice the defense and poise for fast rolling.
Depending on the situation, you can sub in the Ring of the Sun Princess or White Seance Ring for either of the rings in the build. The Wolf Ring is also a good substitution for some additional poise (or any poise at all, if you opt to wear the full Gold-Hemmed Black set for the fast roll).
