After a battle, each defeated demon has a 49% chance to drop something. If it does, each of its items rolls its own chance next, so it can drop both. The game rolls one short of each chance, so a 10% item comes out at 9%, and a 1% item does not drop from a normal battle. Both books drop the same items. 101Leafy researched the game to find the drops.
