So I made it to the final boss in Ys III today and for the life of me I can't beat him. The problem with this boss is you have to defeat *another* boss mere moments before encountering him, and unlike every other boss in the game, you don't regain your health once he's down! And I've tried to go back to the town to get another necklace and healing herb, but it seems impossible. Argh.
Any tips?
