Undead servitors created from the corpses of giant eagles, blackwings patrol ancient sites they were created to guard. They often act as mounts and spies for powerful undead.   Blackwings rely on shock and terror tactics, combining the primal fear of their dives with supernaturally enhanced wailing to terrify their foes. While creatures that manage to take cover are somewhat inured to this approach, this suits the blackwing just fine, as its goal is always to divide its foes and pick them off one by one, starting with the slowest.   Blackwings are fairly resilient, but their wing bones are no stronger than those of the birds they were made from, and can be broken with sufficient bludgeoning force, an especially devastating tactic in any aerial battle.   Blackwings use their Terror Dive, pulling up and trying again on a different target if their first target succeeds on its saving throw. Once a creature fails, the blackwing focuses on it to the exclusion of all else until it is unconscious, then carries the creature back to its lair to pick through its belongings.   Against flying opponents, they use their speed and reach to employ hit-and-run tactics, picking of stragglers and separating their foes.
