Fire Emblem: Shadow Dragon/Chapter 15

Land of Sorrow "Gra's betrayal of Altea years earlier had come as a shock, of course, until that day they attack Marth's kingdom in the name of Doluna, Gra had been a trustworthy neightbor and ally. While the Altean army was out on an expedition, Gra struck from the rearm annihilating the Altean soldiers, killing Marth's father, King Cornelius and stealing Falchion, the blade of light. It was a crushing blow. Much time had passed since that sad day, and much had changed. Now it was Marth's turn to descend on Gra Bastion, and face King Jiol, the man who had robbed him of his father."

Preparation
Before starting, you may want to consider using a Master Seal on your stronger units. Note that the ideal level to class upgrade is 20, but this isn't practical nor is it that useful. Class upgrading at the level of 15-18 is good enough. Having said this, if you can level up to 20 before this, then by all means do so.

Begin
You should have three promoted units. Most promoted units, with the exception of maybe the Paladin and the Bishop, can cross the water, which is an extremely useful ability to have in this battle. Note also that Marth can cross the river too.

I would advise against using Astram, whom you got last battle. Stick to your old party and then start the battle. I WOULD advise taking Beck just to kill the first enemy and maybe pick some other units off.

Give Beck the Arrowspatte from Jake. Also be sure to give a master key to one of your units that can cross the river (like Shiida).

At the start of the battle, use Beck to use Thunderbolt to kill the first ballista. You should get another useful ballista weapon. Next, use your promot- ed units to cross the river. 2-3 of them suffice.

The left fortress is held very tightly by a group of archers. They are a tough group to kill, some of the archers carry longbows allowing them to pile on your units. The house on the island is relatively safe, the thieves are more worried about getting the treasure at the southeast corner.

Of course, using a strong unit like Wolf, you can eliminate all the archers. You could do that, or you can let your units get exp off them (go around them via the river and kill them). Also note that Beck can attack the archers.

Before turn 5 starts, two recruitable pegasus knights will appear. They can be recruited by using Marth. Both pegasus knight will automatically talk to Marth.

If you, the reader, didn't like using Shiida for some reason, these two are a good alternative. For now, just leave the two alone and give the rest of your units the experience.

About turn 8, about right after you recruit the two pegasus knights, more enem- ies appear. They are relatively easy and I like using Beck's arrowspatte to get rid of them. This is also good experience for low level units, you can use Beck (arrowspatte) and Lena (physic) to backup the unit.

Use the master key to open the door and two chests at the southeast corner. One chest contains the ever important Silver Card (halves prices at shop) and a Bullion (S).

At turn 16, the reinforcements of seemingly endless pegasus knights end.

Before taking the gate, be sure to visit the house...

Now, move Marth alllllll they way to the throne and seize.

Save the game and we can continue.
