**READ DESCRIPTION FOR STATS**
I forgot to go over the stats for the build in the video, so I'll do it here in the description. Level doesn't matter too much, 150 or higher, so at the very least stat-wise:
Vigor - 50 (ya don't wanna DIE)
Mind - 25
Endurance - 30 (whatever puts you at med load)
Strength - 14 (min for Great Katana)
Dexterity - 18 (min for Great Katana)
Intelligence - doesn't matter, don't need it
Faith - 25 (to use buffs)
Arcane - 80
I didn't worry about the flask too much BUT there's plenty of solid options I'll list below...
Wondrous Physick Flask:
-Cerulean Hidden Tear
-Thorny Cracked Tear
-Greenburst Crystal Tear
-Crimsonwhorl Bubbletear
-Stonebarb Cracked Tear
The equipment I used is covered in the video.
