Congrats KrazyKatz on getting the first Dragonlord Codex. Posting this so everyone can see the stats. The skill is an aoe ward that raises the chaos resist of all people in the area. They do not need to be grouped to receive the ward.
There is a bug in the description. It says that the skill protects from shadow damage. This is left over from beta testing, when the damage types were not named chaos and divine, but were named shadow and mythic. This description bug has been reported, but the skill works correctly.
