You need to collect all the Fell Arms to do so. It will probably require quite a bit of backtracking and grinding to do so. But the benefit is that you can use the Fell Arms afterwards. They are considered the strongest weapons but the attack is dependent on certain conditions (requires grinding).

If I ever played a NG+ I'll try to collect them all.
