First, i would love to see dungeons and at the end you get a confirmed devil fruit (random) to give the world a little more interest (ofc hard like add a boss at the end and a few creatures with devil fruit abilities?), second as you get stronger mobs can start maybe learning Haki to give more of a fighting chance as when you reach a point your just invincible, third make some sort of item to help get you out of the water, i get in the show you can't swim you got less strength but in minecraft there's rivers and pools everywhere and when you have something like gear 2 active you can easily fall into one and then there you go no more devil fruit for you.

Do you think this is a good idea?

Good?
Bad?

    Ender Let me help you there bud. Find a Sky Island, and look for Skypiean Traders. Make sure you walk with stacks on stacks of dirt, since thats what they use to trade with instead of belli. You're gonna look for an item called "Bubbly Coral" that will solve your water issue with devil fruits. It makes a bubble around you that temporarily allows you to swim and breathe underwater. Yes, abilities can also be used underwater when you use the bubble. Have fun.

        Yea as streamlander said there are bubbly corals. But also I dont understand what you are trying to do here, you complain about the game being too easy, then you dislike the only existing danger which guarantees that you'd die from it, water.

        If you cant control yourself while using G2 then maybe its a you issue rather than the mod needing a change, just dont use it the way you've been using it until now. Start being a bit more careful lmao
