This item would be helpful to add in keeping the flow of battle going if the main healers die. A DPS or off tank can resurrect the healer and prevent a whip. You can put restrictions on it such as a 10 to 15 minute cool down and you can only contain 1 on your person at all times. This would bring a great strategic advantage to party play and or allow other none healing classes to aid in resurrecting important rolls when they fall from a mistake. it's been used in almost every final fantasy and I think it would prove very useful in A realm reborn.
