Awakening Musa 305k Primal Giant Post ( Marni Realm) 32.5k trash YLS

Seems like i am missing a lot of trash from the previous packs which disappears until i get to the pack again. I tried to lower the packs i kill by 2 as well but still with e , z , and the big monster buffs makes it inconsistent and i am still loosing the trash on packs.
