Detailed Mutator Information

Propagators spawn from enemy buildings, so all-clearing a mission will stop them from spawning. Note that all-clearing Malwarfare and Void Launch does not stop them from spawning, because Suppression Towers and Launch Bays are indestructible enemy structures.

An additional word of warning: On Temple of the Past, the first Propagator will attack the rocks and convert them to another Propagator, thus forcing players to deal with two Propagators on the first spawn. One way of avoiding this is to destroy the rocks prior to the Propagator spawn.

They have 450 HP with 0 armor, are Heroic units and detectors and can attack both, air and ground units within 1 range. They have a movement speed of 1.6.

Below is an image of a Propagator.

Propagators spawn in waves at different times throughout the mission, as shown in the table below:

Mission Time	Number spawned
3:28	1
4:58	1
6:28	1
7:58	1
9:28	1
10:28	1
11:28	1
12:28	2
13:28	2
14:28	2
15:28	2
16:28	2
17:28	2
18:28	4
19:28	4
20:28	4
21:28	4
22:08	4
22:58	4
23:48	5

After 23:48, Propagators will spawn every 50 seconds in spawns of 5.

Propagators can attack all Heroic structures but not commander spawn points, or Zeratul's Artifact Reserve. Swann's Laser Drill, Fenix's Purifier Conclave and Karax's Solar Forge will be destroyed and will start to respawn, with no Propagator Spawning.

The other Heroic Structures will be destroyed and will spawn a Propagator. The player will need to rebuild the Heroic Structure manually. The exception to this is Han & Horner's Starport, which cannot be rebuilt if it is destroyed.

Propagators do not attack any unit with a MapBoss attribute. Therefore, Propagators will attack Data Cores but not Aurana's Transport on Malwarfare. They do not attack Harvesting Bots on Mist Opportunities, nor Artifact Trucks on Cradle of Death, nor the Evacuation Ships on Miner Evacuation.

Propagators can be path-blocked, which can be used to trap them while slower-attacking units kill them off. For more information, watch this video below:

Commander-specific Tips

Dehaka: A minimum of six Impalers are required to be able to deal with a Propagator.
Dehaka: Dehaka's Pack Leaders are Map Bosses and therefore are immune to Propagators.
Kerrigan: Kerrigan's Heroic unit can be used to kill a Propagator with 13 points in the Primary Ability Damage. The video below demonstrates this.
Stetmann: Stetellites can be converted to Propagators. Place Stetellites on unpathable terrain.
Stukov: Disable autocast of the "Spawn Infested Civilian" ability at the Infested Colonist Compound to prevent your units from accidentally engaging a Propagator.
Stukov: Two fully upgraded Bunkers (attack upgrades and Barracks Tech upgrades) or Four non-upgraded Bunkers can kill a Propagator assuming they all attack together. Three Bunkers can deal with a Propagator, but a Bunker will be lost, assuming no micro.
Tychus: Crooked Sam's Moebius Restraint Matrix upgrade will stop a Propagator from moving when Demolition Charge is used.
Vorazun: Manually cast Shadow Fury with Dark Templars to prevent them from accidentally wandering too close to a Propagator.
Vorazun: Time Stop does not affect Propagators timings.
Zagara: With a max'ed Baneling Damage mastery, Zagara can kill a Propagator with a Baneling Barrage and two auto attacks.
Zeratul: Shade Projections generate Propagators when killed by a Propagator.
