Dusk Armor

While in dim light or darkness, you gain +2 AC and advantage on saves against being blinded by nonmagical light, glare, smoke, or visual distraction. This bonus ends while you are in bright light created by a hostile Tier 5 or higher light effect.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
