Wandering Drones

Wandering Drones are summoned near bosses with a 3.9% chance, a higher chance with tougher bosses. They are weak, but if you do not destroy them, they summon bosses. Design A purple triangle slightly bigger than a regular triangle with 3 turrets that summon additional Wandering Drones.

Overview
The Wandering Drones, created by the Defender as an entity with the power to summon bosses as a "last resort" of tank destruction. The Defender and the other bosses do not talk about these entities, in fact, the Summoner is the only other boss knowing about this because the Defender trusted him.
