On a random note. My other two monster ideas were going to be a giant burrow spider. (That happened to be wearing something akin to a "headband of intellect", or perhaps had the ability to devour intelligence. Gaining it from feasting on all the dead adventurers in the Everdark.)  

Or alternatively, a friendly goblin and R.O.U.S companion duo. (That would've clearly had a heart attack in the presence of Phaid.)

Anyway, working on another post now.
