Power of the C'tan: Transdimensional Thunderbolt

Select one enemy unit within 24" of and visible to this C'TAN SHARD (an enemy CHARACTER unit with a Wounds characteristic of 9 or less cannot be selected for this power while it is within 3" of another enemy unit, unless that CHARACTER unit is the closest visible enemy unit). Roll one D6; on a 2+, that unit suffers D3 mortal wounds. Then, roll one D6 for each other enemy unit within 3" of the selected unit; on a 4+, that unit suffers 1 mortal wound. If this C'TAN SHARD is a TESSERACT VAULT, roll for each other enemy unit within 6" of the selected unit, instead of 3".
