Okay so I wanted to see what people have to say about this and whether Bethesda meant for this to happen or not. The Atronach Stone lets you absorb 50% of spells casted at you so if you were to summon something you have a 50% chance of absorbing it. Does anybody find this annoying and whether its a glitch or if Bethesda meant for that to happen?

I consider it a bug. If it were just absorbing summons, maybe not but apparently it also interferes with some perks like shadow warrior and quick reflexes. I can't believe the devs would do that intentionally.
