"This feels like a gumball machine giving random rewards. Plus, this ability of the puzzle, 'Shepherding all living beings,' sounds villainous. If pushed too far, one might even be called an evil god..."
Gary Smith muttered to himself, planning to study it further later.
He was very satisfied with this puzzle.
You must understand, as Lilith said, the puzzle isn't set in stone. It can be improved upon or even…
Evolve!
Consider the Storm Spirit puzzle, common amongst the Storm series. It could enhance pet beasts with wind or water attributes, like a spirit born from the storm, which uses the power of a storm to fight and causes windstorms or rains.
If he can further improve it, sign a contract with many storm beasts, then there is a chance it might transform into the Storm Giant Puzzle, able to manipulate storm disasters and destroy everything.
