More Lost Treasures of the AD&D 2nd Edition Monstrous Compendium
Zack: This is that high water mark Hunter S. Thompson talks about. The monster manual wave has broken. The high point has been reached.
Steve: "I'm attacking this reef with my sword. How many hit points does it have?" *The DM pages helplessly through his books. "I JUST DON'T KNOW!!!!"
Zack: "Roll initiative."
Steve: Can't wait to get Keith and Jamie and maybe Rick in and build a whole adventure around some coral. Snorkel Outing of Elemental Evil.
Zack: Expedition to the Barrier Reef.
Zack: You know the subsequent Monstrous Compendiums featured all the usual retreads of this like "undead coral" and "giant coral" and "coral golem."
Steve: Dire coral.
Zack: From hell's heart, I gently undulate at thee.
Steve: This coral can only be defeated by placing some starfish on it.
Zack: If the party remains stationary for 6-8 months they're doomed.
