The efreeti Prince Rashidi al-Zahar ibn Rath transmogrified an efreeti sultana into this delicate suit of crimson chain mail. The wearer of this armor always feels a slight draft, and sometimes finds it hard to stay focused on a task. This item can be found in the Dungeon Master’s Guide.

Wondrous Item, Very Rare

This book contains coordination and balance exercises, and its words are charged with magic. If you spend 48 hours over a period of 6 days or fewer studying the book’s contents and practicing its guidelines, your Dexterity score increases by 2, as does your maximum for that score. The manual then loses its magic, but regains it in a century. This item can be found in the Dungeon Masters Guide.

Handed down through generations of holy warriors, Oathbinder is a warhammer fashioned from gold, jade, and finished wood. You gain a +2 bonus to attack and damage rolls made with this weapon. In addition, it has all of the properties of a mace of disruption.
While holding the weapon, you can use an action to cast beacon of hope. Once used, this ability can't be used again until the next dawn.

Sentience.
Oathbinder is a lawful good weapon with an Intelligence of 12, a Wisdom of 14 and a Charisma of 14. It has hearing and normal vision out to a range of 60 feet.
The weapon can speak, read, and understand Common and Celestial. It has a strong, feminine voice. It knows every language you know while you're attuned to it.

Personality.
Imbued with the lifeforce of an ancient celestial, Oathbinder is the sworn enemy of fiends and other evil extraplanar creatures. It speaks only when it has something important to say, and can often be openly curt and matter-of-fact when doing so.
Oathbinder is courageous in the face of all that is evil. If its wielder actively chooses to flee from facing an extraplanar evil, such as a demon or powerful undead, and can't provide good justification for doing so, the weapon openly mocks them for their cowardice until the wielder can redeem themselves by defeating a worthy evil opponent.
A protector of life and light, Oathbinder has no patience for those who perform acts spurned by dishonesty and corruption. It strongly protests against any wielder who continuously participates in such actions, and can be very disagreeable when its wielder consistently tolerates others who do the same.

Mace of Disruption.
When you hit a fiend or an undead with this magic weapon, that creature takes an extra 2d6 radiant damage. If the target has 25 hit points or fewer after taking this damage, it must succeed on a DC 15 Wisdom saving throw or be destroyed. On a successful save, the creature becomes frightened of you until the end of your next turn.
While you hold this weapon, it sheds bright light in a 20-foot radius and dim light for an additional 20 feet.
