Perhaps same effect as one on Healing Tree can be applied..?
Though admittedly, I don't see it being very effective in Tyrosh, as a place with populance wholly unaccostomed to "weird" stuff yet. What with major-ish blood sacrifice involved.
Nor do I like leaving this tree entirely without anti-daemonic effect to help our budding inquisition in their duties.
But these circles certainly don't seem anywhat near as grand as stuff we put on other trees..
whatever.
@BeepSmile, wasn't it due to Panacea costing a lot more from a recepient to get an effect?
