Does Wrys has 9 personal Speed? I suppose That He might helpful after promotion with a forge, is Wrys your Garnef Killer?
Since you are doing Gaidens I suppose that you will use Horace but if you see he is too good for the playthrough then you could use some Astram. Etzel can use Excalibur so He might prove useful.
Also post the Weapon Experience so people can get a clearer Idea,,, Wrys could be a Mage and I thinking he is a Curate >.>
Have fun!
Edit: You say you are aiming for the Lowest possible turncount... so you might go back for the boots BUT I would like to encourage you to fiish this without the Boots (or give it to a unit ot named Marth)
