Easy kills around corners
When you have your back against a wall and are peeking around a corner, if there is a guard there, toss a poison rice ball (the one with the green leaf) by pressing [Y]. As soon as the guard picks it up, run around the corner and Stealth Kill. It does not matter if he is facing you, but try to kill him before he eats it. By doing this you can use the same rice ball on multiple guards.
