To revive a character, you do not use the battle
screen. Instead, on the map screen, put your cursor over a character
with a pendant. Push Select-B until the pendant is flashing in
the spells/attributes box, and then push Select-A. A screen will come
up asking you which "hero" you would like to revive. Select one by
pushing A and then place it *anywhere* on the map screen that is claimed
by you. It will place that character there and the character will have
all the spells, attributes, and health that he had before the fight
that killed him. Oh, by the way, a sound will also be made, alerting you
and any other player that you have revived someone. The computer does
this also.
To protect your castles, make sure you keep at least one character on or
adjacent to them Speed is important. Attack before you get attacked.
Listen to the sounds, you'll hear a tone when enemies advance into your
territory.
