Glowing Death

Glowing Death is a variant of the Sand Wasp encountered on Greyhollow Island in Adventure Mode of Diablo III.

Originally, they were supposed to be included in patch 2.3, and appear in the Ruins of Sescheron in, but were moved to patch 2.4 instead.

In-game
Glowing Death are much more aggressive than its desert counterpart, and while they have a spit attack, are more inclined to attack players directly. Their missiles deal Fire damage and fly much faster than normal Wasps'.

However, unlike normal Wasps, they only spawn when a fragile nest (called Glowing Hive) is destroyed, in packs of 4 to 6. Avoiding the nest and not touching it (the Hive itself is completely harmless) is possible; however, as Hives are usually surrounded by other monsters, hitting them accidentally will instanly summon Glowing Deaths.
