Errata's chronicle clarification contained a sentance that caught my eye. Does this mean, in a roundabout way, that Jedza's inevitablity of death cannot damage full health targets? as inevitability of death says:

My english is bit broken, so I'm asking for clarification. When model recieves damage and thus procs black blood in hayereddin's aura, who heals in this situation? A) Other models with black blood (and thus ignoring it) around the pulsing model. B) Other models with black blood around the pulsing model and the model doing the black blood pulse. The last sentance of black blood is throwing me off. "This model ignores damage caused by black blood" => does revitalizing ichor work as a pseudo armor or way to heal other nephilim
