After making sure Bleia was appeased, Leon was finally able to finish preparing for the upcoming mission.
In order to better protect his life, Leon had nearly used up all his resources adding all kinds of items to his inventory, each capable of helping him handle different situations.
The 'Screaming Tree Branch' that he had received when trading with Pedro was one of them.
The Screaming Tree Branch was a unique item produced by nature. If one cut a branch from it and tied it to their skin, it would let out a shrill scream when the holder was struck by a curse. The one Pedro traded with Leon could still be used three times, and was vital for the mission.
Before leaving the Tower, he had to prepare quite a lot of similar items.
