Amulet of the Unnamed Warriors

These amulets come in a set of 6. They are made of Mithril, about 3 inches in diameter with braided vines carved around the edge. When receiving the amulet, the front of the amulet is blank but has a portrait of the recipient on the back.  Amulets will only work for the intended recipient, remaining blank for anyone else. The intended recipient chooses what they would like the amulet to boost for them when receiving it, +10 to speed, +15 Temporary Hit Points, +2 to Stealth.  Once the choice is made, the boost cannot be changed unless by magical means. The amulet has one charge per day, recharging at dawn and the charge lasts for one hour. 

If +10 feet to Speed is chosen, an image of the recipient running appears on the front of the amulet.

If +15 Temporary Hit Points is chosen, an image of the recipient flexing their muscles appears on the front of the amulet.

If +2 to Stealth is chosen, an image of the recipient putting on a cloak appears on the front of  the amulet.

Each day, the intended recipient must proclaim, "I am one of the Unnamed Warriors!" to recharge the amulet.
