I’m gonna spend grails and build a LA Eliwood since he’s 1 more BSt than my Brave Hector (who’s on my arena core) and he is easier to merge. I was hoping to build him with Slaying Lance (def refine), Galeforce, DC, Bold Fighter, Panic Ploy. Is Slaying Lance okay or is Berkut’s lance better? How is the rest of the build? Thanks in advance.
Berkut's Lance imo. With Slaying Lance, Galeforce is at 4 count instead of 5. With BF and Berkut's Lance it goes: Eliwood attacks 5>3 Enemy counterattacks 3>2 Eliwood attacks again 2>0 if the enemy can counterattack. Also, since you're going for a DC build you want to take advantage of the added Res during enemy phase.
What you've got seems fine to me. But if you're interested, there are 2 builds I could suggest. (They aren't cheep, though)
(Def) Berkut's Lance [If you don't care about foddering limited copy units.]
