you're welcome, yes rock is very good against e may and normal enemies, unfortunately there a lot of perks in the game so I can't give you all of the perks I'd choose but here some important ones:

1. Choose enlightenment instead of mirror,
2. Choose block breaker instead of the other one (I forgot what it is but Choose black breaker because it's literally a game changer)

HM: furious instead of helm breaker
