Yes, I have succumbed to 5th edition, too. But look, kuo-toa!

My dormant gaming bug is being rekindled with a game I am starting on Tuesday using the new Dungeons and Dragons (Next/5th edition) rules. Seeing as I have not yet shelled out for a Monster Manual and I am interested in slowly introducing some older monsters into the game, I broke out my 1st edition Fiend Folio and, with a rudimentary understanding of the new rules, I churned out my first pass at adapting the old First Edition Kuo Toa from Descent into the Depths of the Earth/Vault of the Drow/Fiend Folio to the new rules. More or less, but simplified, highlighting what I thought was important, and not at all checked for correct math.

These may or may not resemble the official kuo toa. I don't even know if they made it into the official Monster Manual.
