Anytime ten or more lizardmen are found together, one of them will be a 3+3 HD specimen with 21 HP with 1d4-1 royals, 2d4+4 chroma, 1d4+6 copper (25% it's Red Cuprous). This leader will have the same Morale and saving throws as its fellows, but is BAB +4 and it's bite deals 1d3+1. A defeated leader lizardman is worth 135 xp.
Lizardfolk are primitive reptilian humanoids that lurk in swamps, bogs, fens, marshes and jungles. They may also sometimes be found in subterranean environs. Fiercely territorial, they kill when it is expedient and do whatever it takes to survive. The saurian lizardfolk are thought by some sages to be distant cousins of dragonborn and kobolds. Lizardfolk hate warm-blooded humanoids.
