Scrolls are not essential. You can get away with 73 Virility 315hp (Chopping Blade + King Set) and x6 160hp stew from Feasterra Pot. tho better gears/stew would give you allowance for failure like missing/picking a wrong move or two. 100% stew (Valdo's Kitchen) would remove all hp inflicted on your character so if you have the materials get some of them.

Regen scrolls tho would give more advantage on longer duels as you get a lot of hp advantage out of that. others are quite situational and personal preference on which stuff they want to optimize for farming and stuff.
