Amethyst pieces are destructible elements that cannot be linked. The player needs to link the adjacent Charms to remove them. Amethyst can also be destroyed also through Blasts or Birds.
Amethyst can have up to 3 layers. Every time you link next to an Amethyst or hit it with a Blast, the Amethyst loses 1 layer.
Like the Honeycomb, the Amethyst is not affected by gravity, but the main difference from the Honeycomb is that the Blast’s projectiles cannot go through the Amethyst.
