At the beginning of Chapter 7, there is a glitch that allows you to get an almost unlimited supply of Life Of The Gods and Elixirs over the course of the game, as long as your have access to Tairon's Monastery Annex Save Point. When your first pick up the two chests near the save point in Chapter 7, they will respawn later in other missions. This gives you an almost unlimited supply of Life Of The Gods and Elixirs. This only works for Ryu.
