^ 10 seconds in, almost everyone gets feared,
with Velious gear.

Around 1min 10 secs... same thing... 1min 50secs... again whole raid pretty much. I repeat! In Velious gear (inb4 we have so much PD loot now..)! Bards are also present for this.
I'd invite a dev to try to let Klandicar dragon fear/silver breath (or make a hotkey for each and spam with spell ID) until you see what I mean at different values here.
Try it with 400 magic (currently), and 255 currently. Decide what you think.
