Talk:Prawn Suit Jump Jet Upgrade/@comment-27010407-20180203000142

Stack three of these with the best depth upgrade, and you essentially never need the grappling hook for anything more than assistance with mining. Seriously, it's like jump jets out of a MechWarrior game. You get decent horizontal movement, too; enough to outrun a Sea Dragon Leviathan, if you're fortunate and good at platforming the lava islands.
