A fun build I like to run on NG+ and beyond. Obviously fun to run if you like Final Fantasy VII. No parrying capabilities. Can switch Ring of Steel Protection for Havel's Ring to get a Fast Roll. If not in NG+ you can switch the Great Lord Greatsword for a normal Greatsword from Sen's Fortress or a Black Knight Greatsword from Undead Parish. Great Lord Greatsword is just a Greatsword rather than an Ultra Greatsword, so it swings a little faster while also having a nice asthetic for a Cloud Strife build. The only covenant you need to join is Sunbros to get Lightning Spear.
Elizabeth Mushroom is a must in PVP to get constant regen as well as Green Blossom for max swings with Stamina Regen. Charcoal Pine makes a flame GLGS like Lord Gwyn uses. The damage is consistently in the 1000+ range. Overall, a good build and fun for PVP.
