This glass eyeball is slightly uncanny due to the two brightly colored crystal irises it sports on opposing sides. It helps combatants see their foes even in the darkest of situations. The spell DC of any spell cast by Activating this item is 20.

  • Armor You gain resistance 4 to damage from illusion effects.

  • Weapon (fortune) After you cast a light spell by Activating the eye, your own eyesight sharpens until the end of your next turn. If you fail the flat check to target a Concealed or hidden opponent with a Strike with the weapon, you can reroll it and take the new result.
