Armor of unfeeling question

"For 10...30...35 seconds, your spirits within earshot take 50% less damage and are immune to critical attacks. "

does anyone know if it applies to friendly spirits cast by other party members ? it seems to me that it should'nt, but I'm not sure...

Since it says "your spirits" I'm pretty sure it only means those you created personally.

How to test: take one hero, have her equip one spirit, you also take one, and you also take AoU. Go to the Master of Axes on Island of the Nameless, make the hero cast their spirit, then use AoU and aggro Master to make it attack the spirit. See if there's any difference in how many hits the spirit takes to die, with or without AoU. Then compare to what happens to your on spirit.

Armor only effects your spirits.

Tested it before, only your spirits .
