Mercenaries (chapter)

The prolouge of Fire Emblem: Path of Radiance it is very easy and is used to teach the basic mechanics of the game to new players.You only have Ike in this chapter. Your task is to defeat Boyd and Greil.

Strategy
Just go and attack Boyd and he'll be beaten in a couple of hits. Heal with a vulnerary if needed and then do the same thing to Greil.

Hard mode
You can attack Boyd on your first turn in hard mode. This doesn't change strategy, though, because you should still only need to use 1 vulnerary after beating Boyd.
