Sadness will condense into a cold "silent tear stone", and those who touch it will instantly fall into silent mourning.
Rage burns into flying "scarlet fire flakes", igniting everything in sight.
Fear turns into viscous "shadow pitch", dragging creatures into an immobilizing panic.
Excessive joy will produce colorful and sweet-smelling "laughing mushrooms", inducing the inhaler to fall into an eternal dream of ecstasy until the body withers.
The world does not work in a vacuum. It follows a cold law: "Conservation and Transformation of Emotions." The materialized emotions are permanently stripped from the host, leaving an emotional "hole". A person who vents his anger for a long time will eventually become insensitive; a person who has been stripped of his fear will recklessly move towards self-destruction.
