Peehaa Peehaa no Mi

The Peehaa Peehaa no Mi (pH pH Fruit) is a paramecia type devil fruit that bestows on those who eat it the power to manipulate pH.

Rules

 * 1) The user can manipulate the pH of a substance by changing the amount of hydronium and hydroxide ions contained in the substance.
 * 2) The user can only manipulate substances via touch.
 * 3) Changing the pH of a substance requires an appropriate amount of strength to do, and as pH is an exponential scale, changing the pH from 7 to 6 requires a radically different amount of strength compared to 6 to 5.

Strengths and Weaknesses
The Peehaa Peehaa no Mi is mainly a fruit for stealth and defense, but it's powers can also be used for offensive purposes. Along with the manipulation of pH the user gains a passive immunity to acidic or basic substances, and the ability to detect how acidic/basic a substance is.

Along with the standard devil fruit weaknesses, the Peehaa Peehaa has one other weakness. Anyone can dilute, and therefore change, the pH of a substance by adding liquid to it.
