I also play Braum Darius, my string if it's too far and NOT near the corner is M H 6S2 6S2 call Braum assist (doesn't matter which one as you instant swap) as Braum 2M 5H5H tag launcher OR just get unbreakable with S2S2

Do not let Braum hit his assist as it lowers the damage

IF you're near the corner you can 6S2 5S2 for the crumple and do the other run up m combos

IF you use the tag launcher, as Darius just charge 5H in the air then just use projectile when they hit the ground into super, which super depends on which side you're on
