This is the cleric start to my havel build. I recommend the morning star for a while, I used it until I made it to anor londo to get havels set. But I also used a thieves dagger too get criticals on pvp enemies and the grass crest sheild for defense until I could get the actual set I needed. I'd level faith to 20 and then focus on Strength and vitality. become a sunbro and get lightning spears. once you make it to anor londo get havels set, then join the darkmoon blade. that's how I played this build but it's up to you
