pvp minions

[kevin32]

At a random pvp battle, an enemy necro had somehow animated some bone horrors, right out the gate. How could he do this without any corpses?

[Schmerdro]

He was probably using Aura of the Lich, which summons a Bone Horror without the need of a corpse. Or maybe an ally killed himself with a skill or by equipping a weapon with -1 health degeneration and the Necromancer animated a minion from his corpse. But AotL is more likely.
