FATE "It's Not Lupus" - Eastern La Noscea

Description

Summon your smallshell minion. The mere sight of this wee wavekin may cause severe psychological trauma to those who spent years of their lives on faraway shores culling his relatives.

Journal

As is implied by its name, the smallshell's shell is small. What is not widely known is that unlike normal crabs whose shells grow thicker and, hence, larger as the crabs age, smallshell carapaces actually reduce in size due to erosion over the wavekin's lifespan, until nothing is left but legs.

Tooltip

Got naught but a sea lion's share of crab offal 'twixt them ears, I reckon.
