Amethyst Softshell

Amazing tank pet while it lacks in health it can either use acidic goo into absorb spam to recover quite a fair bit of health every turn or you can take shell amour and absorb to negate most of the damage then when you have taken enough damage you can shell rush out not to mention shell rush hits backline as well

I killed all of the Sea Spireshells I could find around the Coral Forest in Nazjatar and the Amethyst Spireshell spawned at 58, 51. Edit: I should add that having flying REALLY helps.

I have found 2 variations of this pet so far:

smaller rounder shell and larger spiked shell.

Very tricky to reach sometimes but worth it and tbh its a fun element to try reach the rare.

There are two different models -- one has a sort of spiky conch shell and the other has the simpler spiral shown here.
