Bosses better in NG+7 list
I've tried Demon souls, DS1, DS2, ER in ng+
Rest is what I would assume to be cool. Let me know your takes!
Demon Souls:
honestly flamelurker. Would make the fight even more tense.
Not sure about allant? Penetrator sounds interesting in ng+
DS1:
This one I actually did finish in NG+7. 4 kings are much more interesting to say the least. They'll kick your nuts. Artorias, Manus and Kalameet are all very noteworthy in NG+ as well.
DS2:
Fume Knight in NG+ is the goat. Sinh might be cool too.
DS3:
Not sure. Haven't done this so, tell me your thoughts!
Bloodborne:
Amygdala, Ebrietas and Ludwig all sound very interesting with higher dmg and health..
Sekiro:
Genichiro for sure, but not sure about others
Elden ring:
Malenia, Radabeast, Midra, Maliketh, Messmer, Bayle, commander Niall.
Make sure to not use holy fortification for some surprising damage fuckery in Radabeast.
