Ela the Hag

If the party discovers Ela’s secret identity, she’ll offer them access to her secret stash of items in exchange for them not revealing her true identity. Shield of the Craven (requires attunement) - 200 gp: A beautifully carved shield that shines with a pristine polish—you cannot see a single scratch on its surface. This shield has 3 charges. When a creature makes an attack against you with an attack roll higher than your AC, you can use your reaction to activate the shield. You then select a creature you can see within 30 feet that is friendly to you. All damage you would receive from the attack is transferred to the friendly creature instead, regardless of whether the original attack roll would hit the friendly creature’s AC or not. A friendly creature is not a neutral creature—it’s not a cow on the side of the road or a scared farmer witnessing the fight. The shield regains 1d2 (a coin flip) + 1 expended charges daily at dawn.
Pearl of Pain (requires attunement) - 300 gp: A black pearl that catches the light with a subtle red sheen. You can use an action to activate the pearl of pain. When you do so, choose a level of spell slot you wish to regain, and the pearl will give it to you. Immediately after, it will take a number of hit points equal to 15 x spell slot level. (So, if you regain a third level spell slot, the pearl will take 45 hit points from you.) The pearl ignores temporary hit points. Your hit point maximum is reduced by an amount equal to the hit points taken until you finish a long rest.
