New Tales identifies water, lava, toxic waste and corruption as substances with their own properties that react dynamically with the world, fauna and One.

The official description says these combinations can create chain reactions, but it does not publish a complete reaction table. Experiment safely instead of treating an unofficial list as definitive.

Q: Does the official page list every reaction?
No. It names the substances and dynamic interaction; exact outcomes should be verified in the game.
