Mostly depends on how strong you made your units and on what mode you're playing. If
you're on easy mode, run Haar and Heather around and you shouldn't have a problem stealing
a few things. The flying units like Elincia, Marcia, and Haar are really helpful if you
leveled them up a lot. I would say to keep Haar near the west where there's a little
opening for enemies on a lower platform to barge in and one of your strong units on the
little opening near the east where enemies can come in and have Marcia and Elincia clear
it from the other side, and watch out for the bowmen. Then once most of those enemies are
gone, send out some strong units and go on a rampage and destroy everything in your path
until you kill the boss. If you're on normal mode, I would say to basically keep the same
strategy, it will just be a little more difficult. If you're on hard mode, though, I would
suggest just keeping up your defenses and not going for killing the boss. Keep your
high-defense units in the front guarding the openings into the castle area and attack with
long-ranged weapons from above. And be sure to make good use of Leanne, she's pretty
helpful.

I guess stockpiling bonus experience was kind of a bad habit to pick up from previous
games. And using cheap weapons. What always got me in this part was the one general with a
hammer that kept killing Brom, and the ****** bowmen on my side that wouldn't stop
attacking the people with treasures even after I told them to go away.

you should try getting callil and also keep everyone near the keep.if you have haar as a
dragon master then get the silver greatlance for him
