Berbalang's Talent

You have developed traits similar to those of a berbalang, granting you the following benefits:

Ability Score Improvement. Increase your Dexterity or Intelligence by 1, to a maximum of 20.

Berbalang's Expertise. You gain proficiency in Arcana, History, or Religion.

Berbalang's Magic. You learn the speak with dead spell. You can cast this spell without expending a spell slot. You can cast this spell in this way a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. You can also cast this spell using spell slots you have. The spell’s spellcasting ability is Intelligence when you cast it with this feat.

Spectral Duplicate. As an action, you can create a spectral duplicate of yourself in an unoccupied space you can see within 60 feet of you. While the duplicate exists, you are unconscious. You can only have one duplicate at a time. The duplicate disappears when you or it drops to 0 hit points or when you dismiss it (no action required).
    The duplicate has the same statistics and knowledge as you, and everything experienced by the duplicate is known by you. You and the duplicate share the same spell slots as well feature usages. All damage dealt by the duplicate’s unarmed strikes or natural weapon attacks is psychic damage. When the duplicate gains the benefits of a short or long rest, you must succeed on a DC 12 Constitution saving throw or the duplicate gains one level of exhaustion, if you fail the saving throw by 5 or more the duplicate suffers two levels of exhaustion. When you gain a level of exhaustion, the duplicate gains two levels of exhaustion. For every two levels of exhaustion the duplicate has, you have one level of exhaustion. Any levels of exhaustion that the duplicate suffers can only be reduced by magic.
    Once you use this feature, you can't use it again until you finish a long rest.
