Minor Treasure—Buoyant Disease!
It influenced the target it had fused with and granted them the Buoyant Disease. It was no different from a death sentence to the average Cooter Clansman whose build was based on fluids.
But for Wally, with Subtle Terrain Domination, he had no issues. The Minor Treasure strengthened Wally's Buoyant Disease and reinforced it. He was already born the perfect Snapper. Therefore, the Minor Treasure didn't give him any growth benefit.
It couldn't improve something that was already perfect. However, its biggest role arrived not in Wally's regular life, but when he ventured into the Sandy-Grey Void.
The Sandy-Grey Void was already dangerous. But with Transcendents arriving from multiple continents, not to mention Cosmic Beings drawn thanks to the pillar of light Brangara had released a few times, the Sandy-Grey Void surrounding Sumatra Continent was ripe with Transcendent Influence.
