Notes from author
Tired of the usual co-op, beat em' ups? Tired of the invading and ganking? Well why not try the healer build? At level 50, you can match easily from Anor Londo and beyond and would add a different play style to your game.
The character was built for style, but if you want to be more effective, feel free to swap some equipment (such as the Maiden Hood to the Dusk Crown or Sanctus to a 100% defense shield), but the set-up should work fine and also keep the general position and atmosphere of your chara in place.
You'll need to get through NG+, but once you do, you should have 2 x Soothing Sunlight and 2 x WoG at your dispense. Use Soothing Sunlight as your primary to save your host or to heal yourself (pop Humanity only if you have to). Cast it when you're summoned to show you can cast the spell.
You won't have many fancy weapons to choose from, so work your way through with your favorite weapon (I like the Caestus since it's light, fast and who doesn't like punching your enemy in the face or parrying and giving a groin punch?). Use your Black Firebomb and Posion Throwing Knives for additional damage. But, that doesn't mean you're weak. Unleash the power of WoG when you need them, and with 6 uses, that should be more than enough to get your host through any troubles.
What's good about this build is that you can always feel free to swap your attunment slots as you need, so feel free to change the character set when you want, but becareful of your Health and Endurance. They basically suck, but most you meet up should be 1st run or NG+, so you should be able to handle fine.
Try this one out and show your host that you were the right summon (like, how often do you see anyone using Soothing Sunlight anyways?). Praise the Su... Boobs!
