Spawns a random Harbinger familiar that changes every 10 seconds. Harbingers have different behaviors and spawn themed Locusts.

"Lil harbingers!"

Spawns a random Harbinger familiar that changes every 10 seconds. All harbingers deal contact damage to enemies and periodically spawn locusts if Isaac currently doesn't have any, though each harbinger behaves slightly differently:
- Famine wanders around the room, leaves a trail of slowing black creep, spawns yellow locusts, and deals 0.5 contact damage per tick or 15 damage per second.
- Pestilence wanders around the room, leaves a trail of green creep that deals 1 damage per tick or 30 damage per second, spawns green locusts, and deals 0.5 contact damage per tick or 15 damage per second.
- War chases enemies, moves faster than the other Harbingers, spawns red locusts, and deals 1.5 contact damage per tick or 45 damage per second. However, War spawns locusts at a slower rate.
- Death chases enemies, spawns black locusts, and deals 1.5 contact damage per tick or 45 damage per second.
- Conquest wanders around the room, spawns two white locusts at a time, has no delay on the rate at which it can spawn locusts, and deals 0.5 contact damage per tick or 15 damage per second.
