Combat brain - every behavior cites its line (8 rules)

Built only from this entry: stat-block special attacks, the printed Int score, the creature type, its feats and senses, and the behavioral prose of its own description. Nothing invented - an uncited behavior is a test failure.

From the entry

Three times per day, a pit fiend can spend a minute to transform nearby lemures into other lesser devils. A pit fiend can transform one lemure for every Hit Die the pit fiend possesses. It can then reshape these lemures into a number of Hit Dice's worth of lesser devils equal to the number of lemures affected. For example, a typical 20 Hit Dice pit fiend could transform 20 lemures into two bone devils (10 HD each), or three bearded devils (6 HD each, leaving two lemures unchanged), or any other combination of lesser devils. Lemures to be reshaped must be within 50 feet of the pit fiend, becoming stationary and unable to move once the shaping begins. After a minute passes, the lemures reform into the shape of a new lesser devil ready to follow the orders of the pit fiend. Although pit fiends can, technically, elevate a mass of 20 lemures into a new pit fiend, most are hesitant to do so...
