Gigantic Chaos Spawn [LEGENDS]

At the start of your hero phase, roll a dice. On a 1, this model suffers D3 mortal wounds. On a 2+, you can heal up to D3 wounds allocated to this model. If you roll a 2+ and no wounds are allocated to this model, add D3 to its Wounds characteristic for the rest of the battle instead of healing D3 wounds.

This unit can be included as an allied unit in an army whose general has the Chaos keyword.
