Notes from author
More for roleplaying than optimized PvP, but still plenty viable. Just a shame about that midroll - but a god doesn't need that. Inspired by an image guide and modified so it isn't complete shit competetively.
Your second ring can be just about anything, and your shield can also be an effigy shield. The giant helm + brass gauntlets with the waistcloth look pretty godly and reach 21 poise, similar substitutions are okay other than the waistcloth and naked chest.
Other godly/lightning weapons include dragonslayer spear, silver knight spear, crescent axe, great lord greatsword, even a dark hand.
The pike can go divine with slightly higher total damage with half of it being magic, I haven't tested which would do better after resistances. Pikes are buyable so it doesn't matter.
