Chapter 19xxH: A Glimpse in Time
Chapter's objective: Seize the throne.
Note: In the game this map has fog, it was removed from the image so that you can see what is there.
Amidst the darkness many knights remain hidden, so you know what to do, bring magic users, the Wolf Beil, the rapier, a hammer, axes, etc. There are two troubadours, one with a Sleep staff, the other with a Silence staff, that you should finish off as soon as possible, one of them is close to the chests and the other is in the middle of the map. And take Florina, make her rescue any unit and make her carry 2 Door Keys, this way you'll be able to enter through the top left door which will allow you to strike from behind.
There are 2 ballistae (one where you start and another one around the middle of the map), so take Will or Rebecca to make use of them.
Teodor is stronger than Aion, but dark magic is heavier, it's recommendable to attack him with fast characters. Beware of his Eclipse, it's a long distance tome and will cut in half your HP upon hit, but it's accuracy is so low that if you take characters with great evasion, he'll never hit with it.
