Usually whenever there is s Threaded Specter, combatants go after it and not the player. Even Hive Guardians spend supers into Specters. However, husk's pilots (worms released after husk is destroyed) ignore Threaded Specters completely, they go straight towards the player. This is especially harmful in the Nether where you can meet tons of husks. A attached a link to a post with two clips. The first one shows that miniboss hive Guardian is foolish enough to super into Specter. The second shows that pilot of minor husk ignored my Specter.
