hey guys I have made another video of beating the endgame in two turns without the life or death skill
The skills I equipped on my Corrin are draconic hex, elbow room, defender, aegis, and armored blow. My secondary class is a +magic, -luck cavalier.
My Corrin has base attack of 32 and a base speed of 33. Xander has a base attack of 34. If Corrin didn't have enough strength I would substitute Aegis
for Dragon Fang, and feed him some skill boosts.
What I did that was really different from the previous video was having a unit with the shelter skill to do the double dance trick.
(Silas "shelters" Azura and Percy will pick her up through the transfer command and then I switch back Azura, who can still sing again).
I also have Corrin attack first just to get the debuff on Takumi, and then have Xander to finish him off.
Based what I have read from around this forum, I should have used a staff user with a higher skill than elise. (i.e strategist flora or jakob).
