Notes from author
Needs skill to evade most attacks, as it doesn't rely on a strong shield (but it has the stats to equip Artorias' greatshield, for example), but can easily take down most bosses in short time with an extra fast stamina recover, which could be further improved by using green blossoms.
The longbow +15 scales great with this dex build and - paired with an hawk ring - gives you the chance to easily snipe off lots of enemies without even get in touch with them, as they won't aggro, most useful against Anor Londo's giants.
I usually use this build as a swift character, relying on fast weapons and light equipment, but its stats are quite balanced and it could be used in other ways, as a strong 2h weapon (I also use the obsidian greatsword) or a heavier armor (I tanked the four kings in full Havel).
