I have a DH and I keep getting WRECKED on GR's when the monsters have reflect.

Any advice on maybe switching out my gear or anything or skills?

Here's a link to my DH

stop attacking when threy glow with big red spikes xD

You rolled the wrong stat on your kridershot, and your meticulous bolts doesn't have good enough rolls to be usable.

I would switch to the multishot build and drop the krider. That being said though, there's absolutely nothing you can do as a kridershot DH when there's reflect damage. You just die since your lightning balls are already on the way, and will be for some time.

Skip or alt-f4, the latter normally saves more headache

There's nothing you can do with a glass cannon, other than stop attacking.

I'd wait a bit before they pop their reflect and then start attacking.

Wait for zSader or zWD to lock them down before you go hog wild, only solution.

shadow power?
