THOOM! The ocean swell crashes into the sea-caves beneath your feet and jets through the blowholes before you, drenching you in a briny shower and dressing you instantaneously in an outfit of seaweed.
Crab Rock began as a relatively simple coastal battle field for our Colossal Crab, but along the way we added small but significant elements inspired by the coastline natural to my corner of Australia.
Chief among these elements are the blowholes: ocean-fed geysers that might explode powerfully in a column of seawater at the end of each round. Not only do they make for natural land mines, but they are great delivery systems for sahuagin reinforcements!
