Giant ravens are cunning predators who hunt in flocks and sometimes associate with evil creatures.
Giant ravens resemble normal ravens, only they stand around 8 feet tall with a wingspan of up to 20 feet. Their eyes are red and have a sinister glint to them.
They attack any creature that seems weaker than them, swooping from the sky and going for a quick kill. They are able to eat almost anything, from cattle to crops to carrion, and some have developed a taste for the flesh of intelligent creatures.
Giant ravens mate for life, and can live up to 50 years. They raise their young in the spring, and the 2-4 hatchlings are ready to join the flock in a month after hatching. The young ravens reach full mature size by the end of their first summer.
Giant ravens speak Common, Auran, and Sylvan.
Combat
Giant ravens typically swoop down upon their prey, using group tactics to overwhelm their opponents. They routinely use wolf-pack strategies, using flanking, feinting, and other tricks to defeat their enemies. They delight in tormenting weaker foes. The flock will usually flee if resistance is proving too strong, or more than half of their number are slain.
Solitary giant ravens usually attack to defend a nearby nest, attempting to lure away intruders, but they fight to the death if necessary.
Training a Giant Raven
Training a giant raven as an aerial mount requires a successful Handle Animal check (DC 24 for a young creature, or DC 29 for an adult) and that creature must be willing.
Giant Raven eggs are worth around 2000 gp each on the open market, while live chicks are worth around 3500 gp each. Trainers typically charge 1500gp to rear or train a giant raven, and riding one requires an exotic saddle. A giant raven can fight when carrying a rider, but the rider cannot also attack unless he succeeds at a ride check (See Ride, page 72 Core Rulebook I.)
Carrying Capacity: A light load for a giant raven is up to 300 pounds; a medium load, 301-600 pounds; and a heavy load; 601-900 pounds.
On the Coast
Giant ravens serve as mounts for the dreaded elite Skyknights of Vinimar.
