Morghur's expansive spirit leaks out of him, for it is too large to be contained within physical form and it affects all but the most strong-willed of living things. Creatures are mutated horribly, their skin splitting open as their bones and muscles grow in random fashion, often merging two or more beings into a single, horrific new Spawn. Missiles that would strike him change in the air, turning bullets and arrows into birds or frogs, cannonballs into harmless puffs of smoke.

Spirit-Essence of ChaosURL Copied!
In the Beastmen Shooting phase. any unit (including friends) within 8" or Morghur take a Leadership test. If failed, the unit suffers D6 Strength 4 hits with no Armour saves allowed. It one or more wounds are caused, then a Spawn of Chaos is created under the control of the Beastmen player (so long as you have appropriate model - if not, no Spawn is created). The Spawn has a Starting number of Wounds equal to the number of Wounds that were caused. This newly created unit does not award Victory points.
If created from an enemy unit, the Spawn is placed into base contact with the centre of the unit's front if possible, and counts as charging in the following Close Combat phase. Friendly units test for panic if sustaining 25% casualties due to the Spirit-Essence. The Spawn is placed 1" away from the unit as Close as possible to Morghur.
Beastmen instinctively keep their distance from Morghur, and so Morghur may never join any unit.
Any model, friend or foe, in base contact with Morghur at the start of any Close Combat phase suffers an immediate Strength 4 hit with no Armour save allowed. This occurs before any other attacks are made, including Chariot impact hits and models that always strikes first. Note that these wounds do not create Spawn of Chaos.
Any missile attack or spell targeted at Morghur will never effect him unless the shooting unit or spellcaster is within 12" of him. In the case of templates, if the template would touch Morghur, then the whole shot/spell is ignored (though it from a war machine, then it may still misfire).
