Crystal Snail

Massive Sluglike creatures who create armor from the rocks around themselves and are entirely sustained by arcane energy they derive from cosumned gemstones.

Arcane Shell
Over the course of many years, most of these creatures have ammassed an excess of gemstones they begin incorporating the broken down materials into their shells. The result is a massive collage of beautiful intricate colors, which also form a conductor of arcane energy intimately paired to the snails essence. Their shell not only serves as an emergency resource for the creatures sustinance but also allows it to perform rudenmentary magic, usually nothing more complicated than elemental or protective spells.

Corrosive Touch
One of the creatures most unusual and unique features is its corrosive form. The substance is powerful enough to dissolve gemstones in mere minutes, but the creature seems to be able to control its own acidity using some kind of arcane power, as it will never melt through the floor it stands on, and even against flesh the substance seems far less damaging.
