I've been playing again after years away and this seems to be working differently than I remember. I remember when it was new thinking it was the best thing they ever did for clerics (right up with our faithstones to port home!). I thought it worked zone-wide but was using it yesterday and it seemed like maybe it had a range? Twice it failed to heal the puller when I used it and yet I know it went off because it was on cooldown plus I got a message that I'd been healed even though I and everyone in the group other than the puller was at full heath. Also, is it still agro free?
Range is 200, a.k.a. heal range. Since it's an AA not a spell, it's a little shorter than regular heals since your ring focus won't work on it. It's still 0 agro.
