The Hive

The Hive is an randomly found in Battlefields of Eternity in  of Diablo III. It may be nominated a bounty.

The Nephalem may find a cluster of crystals that turns out to be a huge nest of Scouring Chargers. When disturbed, each of the three large crystals will spawn a large, but finite, number of the Chargers and Lobbers, including one-two large Praetorian ones. Originally, they could summon them infinitely, but this was nerfed in one of the patches to prevent exploiting. Upon destroying a crystal, a horde of Chargers will appear as well.

Upon destroying all three crystals, Ixatla will spawn, along with her retinue, and spawning more Chargers and Lobbers after each charge. Killing her ends the event, rewarding gold and experience.
