Conch Shell enemy line

The Spiral Shell is a specie of monster found in Golden Sun: The Lost Age. This monster, resembling a small blue snail whose "shell" is its own striped wormlike body wrapped in that shape, is the only monster in either game that is a randomly-encountered non-unique monster who does not have any palette swaps serving as enemies elsewhere.

The Spiral Shell features 155 HP, 21 PP, 268 Attack, 92 Defense, 117 Agility, and 9 Luck. It has strong resistance to Jupiter, but is less resistant to Venus and Mercury, and it is vulnerable to Mars attacks.

The Spiral Shell can attack with a physical attack, and can use the monster skill Poison Gel, which contrary to its name resembles red steam gathering around and into a single Adept. Poison Gel does no damage but may afflict Deadly Poison.

Felling a Spiral Shell yields 236 EXP, 129 coins, and in uncommon cases, an Elixer. It is fought all throughout the Great Western Sea while on ship, as well as when sailing through the Northern Reaches. What makes Spiral Shells all the more unique as monsters is that they appear in large groups between 2 and 5 individuals. If a lower-level party just enters the Great Western Sea and battles five of these at once, they could be quite damaging, though wide area-of-effect Psynergy like Mother Gaia and Cycle Beam would be ideal to take them out en masse. Individual Spiral Shells are quite easy to defeat on their own, compared to Turtle Dragons which have improved stats and abilities everywhere and have over twice as much HP.
