So last night I was running Zul Gurub and just between the final 2 bosses on that bridge where you get rushed by 20 or so non elites, I spammed holy nova and it was glorious. This opens up a whole new world for this spell besides being my critter killer extraordinaire. I can already see myself using it on the non elites in stonecore, and ..... well .... er......other places too.
It's too bad, because I think it's kind of a neat spell but there really isn't any use to it right now. Oh well, maybe I'll find another spot for it.
Oh and it was Zul Aman as someone pointed out.
