As everyone knew, seawater and Seastone were the eternal bane of Devil Fruit Powers users!
Even Whitebeard, the strongest man alive, would drown if he fell into the sea. Lock him in Seastone cuffs, and he could no longer unleash his world-destroying Vibration.
But what Loa had found was a way around that weakness.
At Loa's words, Caesar's eyes lit up. He nodded earnestly. "Yes! The PYRBBRIN Keratin Particles in Seastone and seawater don't directly nullify a Devil Fruit User's Devil Fruit Powers. They suppress the user's ability to use them. They also counter things created by those powers, but they can't make them vanish outright."

Managing to walk normally while wearing Seastone cuffs already takes extraordinary willpower! But that still isn't enough. Seastone restricts what the body can do, raising the minimum threshold for using a power. That's what causes the suppression! As far as I know, no one can meet that threshold while restrained!"
