| Position | Loot Dropped |
|---|---|
| 1 | Axe of Zoltan |
The strongest axe in the game, and held by a required enemy. Worth getting, which you will, regardless of choice.
There are no chests in this map.
| Tiles | Description |
|---|---|
| Wall (Breakable) | HP 20, Impassable until destroyed |
| Edifice Fence Rampart |
Navigable only by fliers |
| Forest | 1 Prt, +30% Avo, except for fliers |
| Thicket | 1 Prt, +20% Avo, except for fliers |
| Onager | 1o Mt, 15 Durability, 3-10 Range, cannot be used by mounted or magic units |
| Heal Tile+ | 1 Prt, 1 Res, +30% HP each turn for non-fliers |

You must defend the inside of the monastery, if any enemy unit makes it to the highlighted tiles you lose the battle.

There are two ambush spots where enemies will come out of the trees upon your units approaching. Flayn will be in Ambush Spot 2, and you must defeat her to proceed.
The Knights of Seiros will attempt to set the town on fire. If you haven't recruited them, you should defeat Shamir and Alois as soon as possible to prevent this.
The two spots marked above will have enemy units coming out of the trees upon crossing nearby. Be prepared and do not let lone units charge forward!
