You kinda need them for the bells to buy upgrade items tho. It’s quite easy to fuck up your build and invest in a really shit weapon. Also very rarely ome of those dungeons may actually have something really unique and cool in it so the lootbox addiction continues. Am i gonna get a super unique cool area with quests and unique bosses? Or another lava slug that drops 1 upgrade item. I ended up looking at an online map to find what i cared about and ignore the rest cos zigzagging across the map to find things organically was very very boring
