But it is easy. That's the point. I think it should be more "challenging" in the sense that it should require some creativity to solve the issue. I mean, you are right, getting regeneration is a creative solution, but isn't that a bit to RNG-based? I don't think the player can be expected to have a beacon with only a lvl 1 blood altar, which leaves mainly potions, which apart from the fact that I generally dislike consumables (I know that the mod's balance should not be catered to my tastes), require either ghast tears (unrealistic) or melons (which need to be found). Maybe I just didn't look enough into solutions yet, though, which is why I asked here.
And not to get philosophical, but I think it's absolute nonsense to talk about "commitment" with regards to games. The only time where "commitment" to a game would be appropriate would be if you want to become a professional player at said game.
