i got this from another person but pack ike with a lot of elixers and dont use them before hand. When renforcements come make mist retreat. they wont attack ike. If you beat him then ena and nasir should join you.

You have to be very lucky, Mist must be a valkyrie, and Ike must have aether. If Ike uses
Aether you can kill him. If not too bad. P.S. If you kill him you get Nasir only, if you
don't you get Ena only.

give Ike a Hammer!!!!!!!

ike can only use swords in this game and a hammer just so happens to be classified as an
axe.
