Aigus

This shield is crafted from Tarom and has had many rituals performed during creation from both Gaius and Atlahneen, and also has been cooled by Atlahneen's own breath weapon, which has made it incredibly light, cold to the touch, and it has a faint white glow. It is emblazoned with the Holy symbol of Illian, allowing the attuned wielder to use it as a holy symbol, given they are a worshiper of Illian.

If someone tries to attune to the item, but is not able to, they make a DC 15 Wisdom save, or take 5d4 psychic damage, and Altahneen and his descendants become aware of the items location for 24 hours.

The wielder gains +1 to Armor class.

The wielder gains  +1 to their Spell Save DC

The wielder gains +1 to saving throws versus spells and other magical effects.

The Shield has 3 Charges, you can expend a charge to cast Hellish Rebuke, except the damage type is changed to cold. The shield regains all its charges on a long rest.

The shield has a magical symbol on the inside of it which is the makers mark of Gaius.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
