"Certain souls are stronger without the max level, well thats the use I found for it." is what refaze said, by which I assume he means: some souls are stronger on a lower level(like a level 9 soul being stronger on level 5 or whatever. And I have never found this to be true. sorry if i misunderstood
You better think twice before you start flossin, I been in your bathroom often
Certain souls are more powerful under level 9, yes. Persephone is the main one, at level 9 it summons Persephone herself, who flinches every time she gets hit. At level 1-8, its just the flinch-free vaccuum.
