soulslike girlie looking for a co-op partner (ps5)

hey lampbearers, my goal is to get the umbral ending. ive beaten this game last year but got the normal ending, so ive restarted my game to aim for the true ending.

i currently just beat the infernal enchantress.

i already know to not cleanse any beacons and to not use the rune of adyr without withering it first. i just need help with these tough bosses
