Taking Fort Merceus Battle Tips
Defeat Death Knight Before He Runs To Win Battle
The main commander in this battle is the Death Knight so you need to defeat him to claim victory. When you approach him, he'll try to run away so be sure to defeat him before he leaves the map.
Place Units In Tiles To Stop Reinforcements
Reinforcements in this fight will keep coming in from specific tiles around the map. To stop the reinforcements from pouring in, you can leave a unit in the specific tiles
Two Chests Contain Items In Map
There are two chests in the right side of the map and they contain a Speedwing and Aurora Shield. Use either a Flier unit or Mounted unit with Chest Keys to quickly grab the items before the fight ends.
