Armor description states :
Ignore a single incoming hit every 10 seconds. As long as you haven't taken damage in the last 10 seconds, your gadget energy recharge rate is increased significantly.
However, there is absolutely no change in gadget regen rate with this armor equipped. The effect where you ignore a single hit every 10 seconds is working correctly but the energy regen does not. I tested this both in and out of combat by spending energy and watching it regen, even tested taking a hit then waiting over 20 seconds without taking a hit just to be sure, still zero change in regen rate.
