The Trainer's Challenge: Qua-Ro Whitebrow

This is easier than the other trainers if you do one thing. Take out the images. ASAP. They only have 1,000 hp each, but they generally spawn a fair distance away (my bear swipe wouldn't hit them). A larger PBAoE might be able to hit them. Either way, burn them. Fast. They don't do much damage at first, but once the trainer starts hitting you with Char Burst the images can hit upwards of 50k each.

He recasts the images fairly quickly, so it cuts into your DPS, but if you focus on the images, you should be able to pull it off eventually.

If you have a fast enough interrupt, try to stop his Char Burst, as it adds a +fire damage debuff.

And, as with the other fights, a second person will make it a fairly trivial fight. One focus on the trainer, the other watches out for images.

The mirror images do about 40k damage for each cast they do, it might be better to kill them instead of trying to out-dps them.

This quest requires you to defeat Qua-Ro Whitebrow. He is accessed via conversation and can be found near the questgiver, where he is training his black dragon, Cinder. The fight is fairly trivial, much easier than the other trainer challenges I've seen. He casts Char Burst, which can be interrupted if you're fast, and Conjure Image, a single copy Mirror Image spell.
