Speaking of which
Why last step is repeatable?
If this quest is made like in GBF (kamipro is a hentai clone of GBF actualy), then step 5 is just a flb of soul weapon, soul will be recruited after step 4.
They simply threw the old Soul weapons into the recycling bin... that's... an odd design choice. But fair enough then.
So we just need one of their MLB soul weapon for new soul weapon?
And elements will vary from the base weapon too?
