This summoned chest siphons souls, filling itself to overflowing with the rich spirits of mortalkind. Ever greedy for more, it eventually bursts, sending forth a lethal explosion of imprisoned soul energy to assail all those nearby.
SUMMONING: This endless spell is summoned with a spell that has a casting value of 6 and a range of 6". Only NIGHTHAUNT WIZARDS can attempt to summon this endless spell. If successfully cast, set up this endless spell wholly within range and visible to the caster, and more than 1" from all models and other endless spells or invocations.
PREDATORY: This endless spell is a predatory endless spell. You can move it up to 8" and it can fly.
Soul Eruption: Should a Vault of Souls glut itself too greedily, the captured spirits within will burst free, tearing at those nearby in their desperation to escape.
After this endless spell has moved, roll a dice for each model within 6" of it. Add 1 to the roll if that model’s unit is terrified. On a 6+, that model’s unit suffers 1 mortal wound. Keep track of the number of mortal wounds caused by this endless spell. If the total is 10 or more at the end of any phase, roll a dice for each unit within 6" of this endless spell. Add 1 to the roll if that unit is terrified. On a 2+, that unit suffers a number of mortal wounds equal to the roll, then this endless spell is dispelled.
