Perhaps the possibility of consuming lethice as a mechanic I know the designers are sensitive to game balance but it can be done in a way that doesn't hurt.
You consume a lethice you can add a point in some of your stats as long as you don't break the maximum per level for example... the maximum you can have in one of your strength attributes, willpower would be 20, so you can't exceed that limit and you will also win a percentage of permanent corruption that you will not be able to remove no matter how many times you pray for lumia's boobs
1 Obtain the title of Souls-Eater
2 You gain 1 to the stat of your choice but instead gain 20 corruption points permanently.
I think that currently counting on the new follower you could get 3 soul stones
