Yhorm the Giant in 25 seconds (No Storm Ruler, Melee Only)

So I recently stumbled across some impressive videos by SilverBullet993, in which he beats Yhorm the Giant way quicker than I thought would even be possible with a melee build, which made me want to see for myself just how quickly it can be done with right stats, equipment, buffs and a bit of luck :) I took some time making a glass cannon build specifically for this fight, leveled str, dex and luck to maximize base damage and picked Sellsword Twinblades for their horizontal slash attacks (easy to reach his head with those, also they hit him twice in each attack, so they can stagger him really quickly). After several attempts and equipment/buff combinations I got perfect dps to end the fight in one stagger as well as perfect rng to do it as quickly as possible. Here are some of SilverBullet's speed kills that served as a motivation for doing this: With Dragonslayer Greataxe: https://www.youtube.com/watch?v=vzMOJBVo2W4 At SL1: https://www.youtube.com/watch?v=sQLNkC_lXeo Equipment and buffs: Hollow Sellsword Twinblades +10, Morion Blade, Sunlight Straight Sword (for Oath of Sunlight buff), Pyromancy Flame, Carthus Beacon, Flynn's Ring, Red Tearstone Ring, Lightning Clutch Ring, Pontiff's Right Eye, Gold Pine Resin
