Use the Map To Your Advantage
There are multiple ways to make your units utilize the great map design of this game. While this first tip may seem obvious, you should carefully choose where you place your units on the map.
The best way to do this is to bottleneck enemies. Since Fire Emblem uses a grid-based system, you can easily block one simple square on the map and have enemies forced to attack you one unit at a time. This is much better than taking on 4+ enemies that can surround and easily kill your unit.
Using a high defense character like Marth or Draug to do this is your best option, as they can hold out for multiple turns without needing to get healed.
Keep Terrain in Mind
Terrain is a very important aspect of every Fire Emblem game as it can give you a much-needed edge in fights. It will give any unit standing on a certain terrain type an avoidance boost.
Terrain types suck as forests and forts are common in most maps in Shadow Dragon and the Blade of Light, and provide an extra fifteen and twenty avoidance bonus. Use these accordingly and fights will be much easier.
But be wary of bosses though, since they almost always stand on the “gate” terrain type. This gives them an extra thirty avoid and regenerates their health. Bosses always have much better stats than common soldiers so the added avoidance bonus will make them a lot harder to deal with.
