OKAGE: Shadow King

To revive an ally during battle you will need to have an Energy Flower item, Energy Bouquet item, access to Ari's (Player's) special move Revive at level 32 or access to Ari's (Player's) special move Life Spark at level 51. Energy Flowers appear in practically every shop in the game so buy them there if you need them. You will more than likely obtain this through natural gameplay since enemies can be quite powerful towards the end of the game and might end up knocking out party members. When an ally has been K.O.ed, simply use an item or special move to revive them and obtain this trophy.
