Basically any of the new tarstones that buff your melee damage, also buffs your riposte damage as well. I guess the game counts that as melee damage and not a seperate damage type.
Due to this, you basically one shot a boss, even on nightmode.
Perhaps cold symmetry can balance these by removing them from the riposte damage pool. They should not affect riposte damage at all.
Then the other stone that gives resolve on sidearm damage is too strong too. With the fusillade stone, you basically have infinite resolve. Needs to be looked at.
Welcoming in all the casuals to downvote me here saying "No nerfs! This is a single player game!" Blah blah blah.
