AVP Rift War 1

The hunting captains could cloak their armor with a push of a button, but only in extreme circumstances. By order of the Clan, the unblooded were expected to survive while being seen. It was part of the challenge that would prove their mettle.

The unblooded's armor would shift visual spectrum frequencies as the wearer passed into new locations, but it wasn't as effective as those worn by the adults. This limitation would increase the need for them to count on stealth, and decrease their desire to cling to technology.-pg.26 chpt.2
