Comments: This is a very well designed Tank set that is completely worth investing into. It is a fundamental Tank set so it’s worth golding it out, getting the perfect traits and using prismatic glyphs on it as it’s a set you will use a lot for basically everything.
This is a Tank set that is actually well designed for both Tanking and Group Buffing. It’s one of the few useful Heavy Armor set that exists for group content currently.
The group buff from this set is called Minor Courage which provides around a 3% group DPS increase to all group members. It is applied by simply by taunting an enemy so its very easy to activate and it’s easy to maintain making it the perfect set. This buff has approximately a 28 metre range for everyone you are in a group with.
The other set bonuses are nice Tanking bonuses as we get a lot of extra stats with 2x Max Health and Max Stamina and we get a small damage reduction buff with Minor Aegis.
The none perfected version of this set is still worth using if you are not quite ready for Veteran Sunspire and can’t get it in perfected. The only difference is the loss of 1 Max Health bonus which is not a huge problem, so it’s still worth having because the set is so simple to use and provides such a good group buff.
