I tested the manacles out after I upgraded them, I run a quick match on rumble. Now mind you I'm in shotgun distance with a skrub using a do gooder auto rifle so I'm like this is the perfect time use these perks toss a "mini ghorn" grenade it took his shield off and about 10% health same as the other tracker grenade another pointless ass exotic from your boys at bungie.iono brehs. The Nothing Manacles are nothing special. Haven't got a single grenade kill in 5 matches with good tosses. Axion bolt already does what these are supposed to do anyways
