magic attunement in WC build

[Proxdox]

Not even really sure how to use amp/dampen magic or what exactly they do. Can anyone explain?

Also was wondering why there are 2 points into magic attunement on the frost build. I was considering putting 1 point into resilience and then having an extra point left over in the frost tree for something like perma/coldsnap/blizz/coc. Am I missing something here?

Fighting a boss that does a lot of physical damage but no magical dmg? Then use Amp Magic on your tank to give your heal a bonus to their healing.

Dampen magic can be used more primarily in PvP - especially if you aren't rolling out with a pocket healer. Coming across another mage, lock, shadow priest and having the reduction to magic damage could help.

It's incredibly situational and has zero use in raiding. Not worth two talent points.

it does have a use in specific encounters, however the difference for sure isn't huge
