Obsidan flesh

I was wondering how many people use and are happy with it. I know it keeps you from being the target of enemy spells. how can you actually tell this....I know with mist form that its working when a warrior swings away at me in pvp and misses like crazy. I'm just not that familiar with earth skills really...can anyone offer any advice here even though this is kind of a dumb topic i'm sure to some people.

You'll notice spells failing as you can hear the same little "pffclkkt" sound that fires of everytime you interrupt your own spell accidently by walking while casting (this time it is THEIR spell though). So when people try to spam you drop dead with spells all they and you will hear is the little soundfile.


(And yes, strangely enough you can hear THEIR Spell failing when under the effect of Obsidian Flesh or Spellbreaker. However you can't when interrupting directly (at least to my knowledge))
