Fire Emblem/Hector/Another Journey

HECTOR HARD MODE CHAPTER 11 ANOTHER JOURNEY
(this should work for both hector hard mode and easy mode.)

walkthrough
Start by unlocking the south door and move south using Hector to take out most of the enemies. Try to make hector have the Hand Axe equipped at the end of the turn so he can counter the archers. The thief will open the door and steal the red gem from the chest so steal his Lockpick before he does or just kill him and he'll drop the gem. (try to steal his Lockpick so you can sell it later).

Hopefully the thief didn't open the door to the room with two enemies so you can heal and organise items. When you are ready, beat the two enemies in the next room then break the wall to the lone archer and steal his Vulunery before killing him.

Lastly steal the Vulunery from the boss before killing him with Hector's Wolf Beil (rescue Matthew with Hector when he steals from the boss so he doesn't get attacked).
