Comments: This set gives an good group buff. The problem is maintaining the buff as it has a very small radius of 10m and is rather sustain heavy.
This set no longer activates on people based on their Max Stamina as it did in the past. The buff appears to proc on people randomly however it is somewhat proximity based. To make the buff appear on multiple targets you cannot stand still, if you stand still the buff will refresh on the same people so you always need to be moving to get it onto other people. You effectively need to try and have 2 stacks of people and you would move side to side, out-ranging 1 stack at a time to proc the buff on alternative people.
In 4-Man content if you are comfortable Tanking in Medium Armor you could replace Yolnahkriin since the buff is bigger and it procs on you +5 others it should always hit your whole group, but it can also be combined with Yolnahkriin.
This set only needs to be used on 1 bar, so you use the Staff and an Assault ability on your back bar and then you can use a 2 piece weapon set on the front bar such as the Master Weapons. The staves can be expensive and hard to obtain so you can front bar the set on a 1H and Shield or even use it on the Hands and Waist until you can upgrade to the weapons.
Sometimes you might need to use this set on the body pieces – this is because as an Off Tank you might use combinations such as Elemental Catalyst or Martial Knowledge alongside Powerful Assault and those are Light Armor Sets so using PA on the body will be necessary.
