Was it intended that Merciful Healers were not intended to use the harm feature of the variant channeling, since they are only allowed to channel positive energy, and cannot use said energy to harm undead? Or should they be able to channel positive energy to harm, even if they are of good alignment, and only get the harm benefit from the variant.
Cleric of Milani: Healing Domain to satisfy Merciful Healer requirement; Additional domain includes Protection, for variant Channeling (Heal:+2AC/Harm:-2AC)
Can this cleric use the Harm variant at all?
Some would say that a good-aligned cleric can only use negative energy to harm (and cannot, due the Merciful Healer requirement).
Some would said that a good-aligned cleric can only use positive energy to harm undead creatures. So does reducing the AC of the undead creature qualify as "harming"? (if yes, again, not allowed under the merciful healer requirements)
Some would say that due to the variant channeling, the cleric's deity allows the cleric to channel it power with more flexibility and so should be able to "harm" with positive energy even against living creatures (but only with the variant ability, not the normal half *d6 positive energy damage).
So WSY (what say you)?
