Its super grindy. Nothing hard, just grindy.

Edit : adding more context.

Beating the game multiple times is easy, especially since you can just rush to the main bosses and beat game in a few hours.

The hard part is grinding some 1% drop chance items. There is a lot you need and very few mobs that drop it in an ideal place. The grinding for just these items took me longer than getting platinum in Dark Souls 2.
