Heater Shield Faction: Ironfist Stronghold Nora: 25 Flavor: "It's better than magical, it's metallurgical! - Master Armorer" Equipped champion blocks the first 10 damage dealt to himself or allied champions within 2 spaces each turn. This equipment refunds 3 nora for each point of Defense equipped champions has (up to 15 nora).
So it's a 10 point buffer that refunds nora and refreshes itself every turn? I'd bump the cost to 35 since then it's only a "20 nora" investment, then change the buffer to only block for the equipped unit.
I can see it needing a cost increase. But for the area effect. That was one of the points. An armoured guy can equip the shield for a discount and use it to help defend a weaker unit. Let's it be used as a solo defense equipment or as a supportive equipment
