Alright, Serhiem is going to be using the one saved magic as well as give some tactical advice should he have to. As for the Orc, I say we give him a gift or offer to have him join the clan, while yes his race isn't all that great, this shows that not all of them are bad. 

Edit: 

As far as his action goes, he, along with the craftsmen/whatever party needing to be involved, would like to analyze Eliz's crossbow and see if they can replicate it.
