In leu of the original, I thought it could be fun for the book to store as much xp as it is set to hold upon being crafted

second, the book would be consumed [ala eating or totem animation] and destroyed, returning the xp to the player

I found sometimes the xp would be oddly counted in combination with levelhearts, unlocking new hearts with less than the levels required. this could be an issue on LH's end but idk tbh

This is all things I've thought could make the book more versatile for modpacks
