BC efficency is anything related to BB fill.So any kind of BB gauge boost ability is affected(7* Tilith's SBB can hardly fill enough for ur units to use BB, imagine that),that why 2 turn mitigation is important for this fight.Azurai won't help much here since KM is immune to crit damage,so use OE Sirius would be more usefull because he have BB regen on LS which makes it a bit more bearable
