This is the build my friend and I used to farm 8 original sins with only 2 fails.
Sorry for my stumbles lmao.
Although not budget, it does not require a mageblood but still needs some expensive items like nimis, and ashes. If you guys want a full walk through and game play of how i run sanctums, I have 2 full runs and can upload them along with a full sanctum guide and tips/tricks on how we approach our runs.
