Notes from author
My best attempt at Sundowner from Metal Gear Rising. Get in touch with your inner child, and send your opponents to a fiery end!
Use pyromancy, Black Firebombs, and the Fire Tower Shield to simulate his explosive shields. When the fighting gets serious, whip out your machete and let 'em have it.
(NB: The Butcher Knife's strong attack is unaffected by Iron Flesh, so consider that as a possible melee tactic.)
