Ancile

Armor (shield), legendary (requires attunement)

The Ancile is a large “figure 8” shield. On the shield is a special form of the sign for Ares, an apple surmounted by a spread-winged Victory. It is said to have fallen from heaven and is as a symbol of great reverence and luck. While holding this shield, you gain a +1 bonus to AC. If the shield is on your person, you can call on its luck (no action required) to reroll one attack roll, ability check, or saving throw you dislike. You must use the second roll.

This property can’t be used again until the next dawn.
