Notes from author
This build can counter every other build play style in the Dark Souls 1 meta, as well as many niche play-styles.
Dark Bead builds can be countered by using GMB.
Hornet's Ring builds can be countered by using Tranquil+Bead.
Buff focused builds will be around the same powerlevel as you, as well as having GMB.
You have an exceptional moveset with the Claymore.
(If fight outlasts duration of Darkmoon Blade, swap to a +5 Chaos Claymore.)
