Then again, why would you swim in lava if you could fly over it?
Why are you swimming, or flying over this lava, anyways, when you should be sending an army of turtles to collect the lava?
Ah, right, ILoveGregTech was trying to make a point regarding the usage of the GraviChestPlate. Eh, I can swim in lava for eight minutes at a time with a fairly cheap potion (and with one of my HUD mods, I get constant updates on when it'll run out).
