Gravelord Build Advice

I've recently grown a love for the Gravelord Sword. I've started on a build which i trying to tinker with and tune.

This is what i've got so far, bare in mind i'm not an amazing player at Dark Souls, quite mediocre actually plus i'm held back a little more because i'm an offline player as i cannot gain online access till i get the game for PC instead of xbox.

Lvl. 25

Lvl. 50

Until i'm able to use the Gravelord Sword i'm aiming to try and gain the Black Knight Sword early to start me off then plan to use that as a back up for later in the game if i'm struggling, if not a claymore.

So any advice on tuning this build to work well would be appreciated (:

1.) I don't think you can get 2 pyromancy flames for one character.

2.) The gravelord sword does high damage and stunlocks EASY, so you'll never need to use combustion unless it's to recover stamina while keeping the enemy away.

3.) For the sl 25 version, switch havel's ring to ring of FaP. More HP, more Stamina, still under <50% weight

4.) Changed the SL 50 version so you can take advantage of the gravelord greatsword miracles. It would be smart to usea poison cloud to cover your casting for gravelord greatsword dance.
