Sure. Chapter 5 has 3 spots that need to be blocked. 2 of them can be blocked with Ike + Titania, while the third one would require drafting a GM. Since Oscar, Boyd, Shinon and Soren have all been drafted already, that leaves Gatrie and Rhys, both who are probably going to drag the player down lategame. So I wanted to know if I could use a statbooster on an undrafter character so I could hold one of the spots with Soren or Rhys, and if needed give them the Seraph Robe so they can survive (I have never really found an use for it in NM other than getting Ike an HP transfer, and maybe surviving rocks in Chapter 25), instead of getting 1 extra turn due to using Gatrie.
And since it looks like I can, and I also can use BEXP,
Mist.
