Gift : Master key
The red stats are a minimum. Those that are not can be changed, according to your own taste : Want a more sorcery oriented build ? Raise Attunement and Intelligence. Do you prefer clerical skills ? You will want attunement and faith. The build I use is more close combat oriented, with a few tricks.
Left hand : Greatshield of Artorias / Catalyst of your choice
Rings : Havel's ring / Wolf Ring
Armor : It's up to you. With Havel's Ring, you can wear some heavy armors and keep a good mobility (not too heavy). I'm curently using a patchwork of the elite and silver knigth sets, just because it looks awesome and because... well... Artorias is a Knight after all. Don't be too concerned about poise, because the wolf ring will give you 40.
Spells : It's up to you too, to your style. I'm currently using homing crystal soulmass, tranquill walk of peace, wrath of god, heal.
