Champions of all that is good and just, lammasu have quadrupedal bodies the size and shape of the largest of lions, fully-functional feathered wings, and a human head bearing the kindly visage of a bearded wise man.

Lammasu are the guardians and protectors of all lawful good persons and have a friendly disposition to all good-aligned creatures they encounter. Lammasu tend to lair in warm climates but travel widely and can thus be encountered anywhere.

Lammasu prefer to advise and support the forces of good if at all possible but are formidable opponents in battle. In fact, it is almost impossible to press a lammasu into combat against its will due to its ability to dimension door and become invisible at will. In combat lammasu claw with their two powerful front legs for 1d6+1 points of damage apiece, and they also defend themselves with a variety of spells and spell-like abilities.

Lammasu can communicate in their own tongue, the alignment language of lawful good creatures, and also through telepathy.
