Took a stab at the challenge quest. By the 2nd stage I was already two deep into my sub members. Things were looking grim with Fergus. Somehow Merlin's heal and invincibility skills kicked in at good times to make it through. I really lucked out with both rulers stage 6. Jalter one turned them both… O.o
By Dante's stage I still had Hercules left… Luckily I didn't need him.
Did you have to break the seal? I screwed up on Amakusa and that ultimately lead me to breaking the seal.
+Vincent H no command seals used. It looked bad by the 2nd stage. Didn't think Merlin, Jalter, Cu alter would carry the team through. Prior to stage 6 I built up Jalters np. So with Jalter's crit stars and brave chain with NP (np killed Amakusa) and the crits killed Jeanne in one turn.
+Francis Huang that sounds logical. I thought about doing it again, but there's no drop on second time around.
