You can use a Free Action on your turn to cause the armor to glow with a golden Mage Light, which you can turn off with another Free Action on your turn.
Once per round on your turn, you can use a Free Action and spend 1 charge of Inspiration or Mana Flux to remove 1 level of the Fear condition from yourself and all allies within a radius equal to 10 feet per Tier of the armor. You can do this even if a Fear effect would prevent you from taking such an action.
You can use a Free Action at any time and spend 1 charge of Inspiration or Mana Flux to grant all allies within 30 feet of you a +4 Bonus to saving throws against Fear, Emotion, and Charm effects until the end of your next turn. The radius of this effect is increased by any abilities that increase the range of Teamwork effects.
