I posted the response a bit far after the text was deleted. The main question was about Unholy Aura and how to make it target enemies. There should be more threads about the subject anyhow. My last trigger suggestion is in retrospect not good and has faults so other threads hopefully have better options. The fault I imagine with changing a units stat is, changing default Life Regeneration has an impact on other "stuff", if its reduced and another ability increases/decreases it by % it wont increase/decrease it by the correct value and will return an incorrect value and might even restore an incorrect value after the trigger is completed. I would either let default abilities control all life regeneration or trigger all life regeneration entirely. Tbh I might even cop out and deal damage instead of decreasing life regeneration XD
