Lvl 80 solo

Well, this one is the same for everyone, but since i did it with an elf.....

Pick up the quest at Lime from Tyra.
Run down the road to Spire.
Stay to the right side when entering, go behind the buildings to find the lvl 1 fanatics.
5 of them there; kill them each 10 times (easy kills).
Return to Tyra at lime for your elixer reward.
