Good suggestions. Moonstone Renewer is still bugged as well, so they need to fix that first.
Yeah, sorry for that, the item is still bugged if the user themself is out of combat and they try to renew the buff without damaging an enemy. It should be fixed for 10.24. The original heal instance if the user is out of combat functions correctly, but renewing the buff does not if the user stays out of combat (eg. soraka standing in the back healing, but not damaging anybody) :(
