Magical Disturbances

It's embarrassing to admit this, but something has happened to me here in Terokkar Forest that hasn't occurred since my apprentice days.

Occasionally, my spells will fizzle when I know I've done everything correctly. I almost drove myself crazy the first time it happened.

I think I've found the cause. The forest is full of creatures called warp stalkers, demonic creatures with an affinity for magic and a habit of disturbing magical flows. The best way to deal with them is simply to kill them.
