Fire Emblem: The Sacred Stones/Chapter 5x: Unbroken Heart

Seize the throne
Once you start, switch Orson's equipment with another unit or just avoid using him as much as possible, only using him in certain situations (for reasons later on). Try to get someone with a javelin to get rid of the mage and fighter in the treasure room. Get the Killer Lance and Elixir from the chests and continue though the hallway, minding the enemies range. once you get to the fork in the road, take the path to the right as the left side has more danger with the magic users. The archer to the far right drops an elixir so get rid of him quickly. Be careful once you get to the throne room because the knight, shaman, and monk can really hurt you.

Boss:Zonta
Zonta can be easily defeated by surrounding him and healing when necessary.
