In this video I show you how to get a divine Coiled Snake Kabuto, a rare helmet that gives you 29.9% extra close combat attack when you poison an enemy.
The kabuto is dropped by "Toranoshin the Dilettante", a developer revenant placed early on in The Defiled Castle mission, which you'll find in the Tokai region.
Put as much luck and equipment drop rate/human equipment drop rate as you can on your gear. Note that if you're lucky in reforging, you can also get 25% equipment drop rate on chest armor.
Choose Daiba-washi as your guardian spirit. You can also get more luck via clan Furuta, from allocating your prestige points under the Titles section, and also if you use a luckbringer talisman.
