Fire Emblem: Path of Radiance/Chapter 1: The Battle Begins

You get your first mission as one of the Greil mercenaries and it's to defeat a couple of bandits in a small nearby village. Ike, Titania, Oscar and Boyd are those chosen to carry it out. These four heads off to battle the bandits while Griel, Shinon and Gatrie handle the other requests.

Walkthrough
The aim of this level is to seize the northern-most house. To begin with move Ike up and visit the South-eastern house to collect a steel sword. Then, move Titania into the bottom-right hand corner as she is too strong and will steak all of your exp otherwise. Use Boyd to fight the fighter just past the fence and near to the soith-west house, then oscar should be used to fight the other nearby fighter. Once this battle is finished, move Oscar down one square so Ike doesn't get attacked during the enemy's turn.

During your next turn continue Boyd's battle and finish off Oscar's foe from turn one. Move Oscar towards the north-west house after that fighter's dead. Ike needs to make his way up towards the boss. During turn 3, visit the North west house with Oscar and fight off the western myrmidon and bandit. Now use Ike to deal with the North-eastern enemies during the next few turns with Boyd as back-up if things turn for the worse.

After all the minions are dealed with it's time for the boss. Use vulnerary's to fully heal your side and then move in for the kill. First off, attack with Oscar and afterwards move downward slightly to make room for Ike's assault. Once Ike has fought, end the turn and let the boss fight Ike for the rest of the level. Use vulnerary's if Ike starts to run low on health. Don't worry if there are none left in Ike's inventory, trade Oscar's or Boyd's one to replace it. Once the boss is dead, seize the area and complete the level.
