Flail Snail

A flail snail is a creature of elemental earth that is prized for its multihued shell. Hunters might be lulled into a false sense of confidence upon sighting this ponderous, seemingly nonhostile creature. If any other creature large enough to be a threat approaches too close, though, the snail unleashes a flash of scintillating light and then attacks with its mace-like tentacles.
