Aside from getting them, which may prove timetaking if you're unlucky, this set is great for tanks not only becase of the enmity boost you will achieve but also because of the additional Ice Spike effect which is not 100% but has a high proc rate. Having used the set for WS on some DD jobs I noticed around 1/3 proc rate while being hit during WS gear swap alone.
Amazing peice for Ninja in my opinion, even if only to macro in for provoke. NIN needs all the hate it can get. Got these 1/1 on a Demonic weapon, however to my misfortune & being distracted by a phone call, it wouldn't let me obtain them from the chest. Thanks SE -__- 3 hours later & not even a 2nd brown chest lol
