Fire Emblem: Shadow Dragon/Chapter 15

An Oasis of Magic "Khadein, city of magic. Ever since Gharnef named himself ruler of this mecca for the magically inclined, the sands surrounding it had run red. Many knights had tried to oust Gharnef, but what defense did they have against the mages the fiend had bent to his purpose? One by one the heroes fell to blades unseen and fires within their armor; and it was not long at all before Khadein's wickedness outstripped its wisdom." Not too many comments to write about this battle's preparations, just remember that faster units are key in this map. A thief is necessary also.

When the battle starts, we zoom to Gharnef's reflections.

DO NOTE THAT GHARNEF IS INVINCIBLE. Not even the strongest of units can kill him. You must wait until the end of turn 6 and he will decide to leave.

HE WILL ATTACK YOU if he gets a chance. Before he reaches the middle island, charge with a mass of units forward. The mages have low defence and can give good experience. Just watch for the damage, it accumulates fast. Also use an archer to destroy the dracoknights that attack they are relatively strong.

Anyhow, don't let Gharnef be able to attack any units. All units that can move fast, go north and fight there.

Any unit that cannot, move them to the southwest corner of the map.

At turn 6, Gharnef will say...

With that, he teleports off. Yay for us. There are really no more bosses left, the guy guarding the castle is just normal. However, his attack is a far ranged one and can do some hefty damage. Keep a healer using Physic, or Mend depending if she/he is strong enough to withstand some attacks.

The rest of the map is an experience spree. Bring your thief to the lower right corner to take some treasures.

The boss should be dead and the reinforcements should be running thin at turn 15 or so. Then, comes the interesting part.

In a few Fire Emblem games, there is a sand level like this one. They tend to have items HIDDEN underneath the level. HOWEVER, I have checked this level for the most part and haven't found anything interesting.

If you find anything hidden in the sand, please contact me and you will be added to this list.

Treasures from the southeast corner include:

1) Energy Drop 2) Tailsman 3) Spirit Dust Seize the gate when done...easy chapter except for Gharnef, eh?
