Ok so the Black Knight's exclusive special is called Black Luna, not Eclipse, but more importantly it is a 3 CD special.
The other skill he comes with is Wings of Mercy, that's hilarious.
EDIT: Figured I'd give the new banner the old 1 full summon try and on my 4th orb, bam, +Spd -Def Elincia. Fuck yes.
No new spear units, but I did get Raven with my pull. Gonna try again and hope I get lucky. I got a Sheena whose A skill I transfered to Wendy, I mean Gwendolyn. A Jagen which I'm sent home, a Felicia whose Special I'll transfer to Mathilda once she becomes 4* and a Roderick whose Support skill I transfered to Alfonse. Sharena has a skill that boosts Str, why not have Alphonse have skill that buffs Defense?
Also, even though you guys know this: Black Knight is voiced by Robert Clotworthy. No idea who that guy is.
