Fire Emblem/Blood of Pride

In this chapter there are three blue tiles that have to be stood on to complete the level. You actually have to have a unit "Wait" on the tile for it to activate.

In normal mode the first blue tile is pointed out for you, and the second is in a closed room to the south. To get to the room you need the key from the south village or you can send Matthew round to open the door for you. Once you stand on the second tile, the door in front of the first chest will open revealing the boss and an archer.

Before fighting the boss, you may want to open the top right door. The chest contains the sword Knightslayer, which has increased damage and hit chance against Knights, Cavaliers and their promoted classes. Also, definitely don't forget to take the Angel Robe from the centre chest. It increases the max HP of one unit by 7.

Their are a few strategies you can use for defeating the knight. You can use the Knightslayer from the chest combined with Sain or Kent. You can use Lyns Mani Katti, which also does bonus damage against Knights. You can use Erks magic, because the boss has low magic resistance. Alternatively, you could attempt to use Rath and Wil to shoot him, but he does have a high defence so this isn't reccomended.
