*Thinks Naruto then thinks game play*
A scroll that makes your mount's round full again (summoning scroll), a scroll that give you 1 extra skill point (secret scroll), A scroll that sends a random throwing item at your enemy which last for 10 turns (ten-ten's scroll). Some scroll will cost you 10% of your hitpoints when used because you need to use your blood to draw on it.
p/s: There's no such thing as a scroll that give you more attack & defend or hitpoints. We already have soldier pills for that.
