In the left image, you can see that Luffy and Brook have their powers drained. However in the right image, both Hancock and Luffy are in standing water but seem to keep their powers.

So, does the amount of power they lose depend on the water level?

  • Well, we don't actually see Luffy and Boa maintaining their powers, we just see them not weakened, so that might have a tie-in.

  • @Dragon I believe that was not when she was in the water, because the beam did fire it just didn't do anything.

Based on what I read and what I remember:

  • Rain normally doesn't have an effect.
  • If the Devil Fruit user's body is mostly out of water, then they get weakened a bit.
  • If the user is totally/mostly in the water, they normally can't move.
  • Seastone has an effect like that of being totally in water.

The difference of the above pictures: on the left, Luffy and Brook are mostly in water, so they are very weak; on the right, Boa Hancock and Luffy are only standing in knee-deep water, so they don't lose too much power.


I think the water level is not important, just because when some water is touching them they start losing their power. I think the most important think is the time they are being in contact with it.

    thanks for your answer but i don't believe that's the case because whenever a devil fruit user touches the ocean or the sea stone, they start loosing their power, they may still have enough power to defeat someone, but they do loose their power just from touching it. SPOILER this is show in the bit just after the two year gap where they are underwater trying to get to the mermaid land.
