Status/Elemental Resistance/Damage Absorbtion of Ice Aura.

So it has a party effect? Interesting. Although 20% Stance isn't that amazing, better than nothing.
Say if I have Ice Aura toggled on:
If I cast Infinity, will the +70% Power Stance effect stack? If not, does the 20% stance come back after Infinity runs out? The same question goes for Knight's Watch as well.

Also, does the damage absorbtion affect 1/1 attacks?

I can't speak about Ice Aura since I didn't even know it affected the party? Does it really? If so, are the other effects party? Probably not. An anti-1/1 would be nice, I guess we can look to Battle Mages Blue Aura for that answer, I suspect not, but I don't have a BaM.

But I can tell you that if you cast Infinity after a Knight's Watch, Infinity will cancel the Knight's watch. I only wish Infinity were macroable so I can macro a Infinity followed by Knight's Watch combo since they both have the same cooldown time.
