"Curse Eater: Updated this item set so when you use a Direct Healing ability on a target, you remove 3 negative effects from them. If a negative effect was removed this way, it will restore 600 Magicka. This effect can occur once every 8 seconds."
Does anybody know if Combat Prayer and/or Funnel Health count as direct healing, and if the 8 seconds cool down is per player so it can apply to multiple players within 8 seconds?
