ROC

Rocs are huge birds somewhat resembling eagles. They inhabit the highest mountains in warm regions. They prey upon large creatures such as cattle, horses, and elephants. 

The roc swoops down upon prey, seizes it in its powerful talons, and carries it off to its lair. If the creature resists, the roc will strike it with its beak, inflicting 4-24 points of damage per hit.

The lair of a roc will be a vast nest of trees, branches, and the like. There its treasure will be strewn about, for the creature does not value such... it is the residue of its victims.

Rocs are occasionally tamed and used by giants.

A boobrie looks as if it were a huge heron with a beak resembling a cross between that of a heron and an eagle. There are a number of small, sharp teeth along the edges of the beak.

The gigantic boobrie resembles a smaller, marsh-dwelling relative of the roc. Its favorite foods, other than the huge marsh catfish, are humans and sheep. Its long legs permit fast running and easy movement through swampy ground, but its claws are relatively weak.

They achieve surprise by crouching amidst tall grasses. 

The boobrie's flight is slow. Its principal attack is by means of its long, hooked beak. 

These birds are totally immune to all forms of poison, and if favored forms of prey are not available they will eat snakes, lizards, and even spiders of sufficient size. 

If 2 are encountered they will be either a mated pair of adults (at least 5 points per hit die) or a pair of young (4 or fewer points per hit die).
