Track the abilities of Greyheart Nether-Mages in SSC
This utilizes nameplates, so to get most out of it, make sure to run the following commands first:
/console nameplateMaxDistance 41
And then follow with:
/reload
To make the changes active.
This extends the nameplate range from 20 yards to 41 yards. For the weak aura to trigger, you'll then have to be facing the mobs and be within 41 yard range.
