UPDATE: I lost info to my original account I posted this weakaura from (Khalid), but since I posted it, there has been a change to the ability "Gorefiend's Grasp", the range was reduced to 15 yards down from 20 yards, so basically this is just an updated version that works with the latest version of the ability.
A Weakaura that shows how many targets are within Gorefiend's Grasp range if you cast it on yourself.
The Weakaura will disable itself once Gorefiend's Grasp is on cooldown.
Note: You NEED to have your enemy nameplates enabled and showing for this Weakaura to function.
**This was inspired by Polihayse's Sweeping Strike Weakaura**
