Jormungandr favoured subtler methods than the siege tactics displayed by the other Hive Fleets. Its bio-vessels rarely entered planetary orbit. Instead, Jormungandr snared asteroids and other space debris, hurling them at the target world and launching [[Mycetic Spore]]s in concert. The devastation wreaked by the bombardment ensured that a greater proportion of the Spores make planet-fall. Each Mycetic Spore that landed unleashed a [[Ravener]] brood, or sometimes a [[Mawloc]] or [[Trygon]]. These immediately buried underground and went dormant to avoid detection. Only when the infestation reached critical mass did the Hive Fleet send the psychic stimuli to awaken its slumbering serpents, timing the resultant planet-wide destruction with the arrival of its Hive Ships in orbit. The Hive Ships would then deliver [[Genestealer]]s and [[Carnifex]]es to the surface to escalate the havoc.
