Shadow Resistance: Whenever it takes damage from an attack that is not radiant damage while it is in dim light or darkness, it rolls 2d4, and subtracts the number from the damage taken. 

Dark Form: The Abductor is invisible while in complete darkness.

Planar Traveler: The Abductor is immune to all planar regional effects.

Spellcasting: The Abductor can cast the following spells. Wisdom is the spellcasting modifier (spell save dc: 14, spell attack +6, spell modifier +4)

At will: Comprehend Languages

1st level (4 slots:) Charm Person, Detect Magic, Inflict Wounds, Shield, Silent Image

2nd level (2 slots:) Blur, Darkness, Misty Step

(1/day:) Plane Shift (can only plane shift itself, and it takes 1 minute to cast rather than 1 action)

Axe: +4 to hit, 5ft range, single target, 1d10+2 slashing damage and 1d6 necrotic damage. Anyone who holds the axe and isn't an Abductor will take 1d6 necrotic damage every round until they stop touching it.

Abduct (1/day): A creature within 15ft of the Abductor must make a dc 14 charisma save. On a fail, both the target and the Abductor are sent to a plane of the Abductor's choice, both landing in spaces in that plane within 15 feet of each other. If the target kills the Abductor that abducted it, it returns to the space it was in before it was abducted, landing there prone.
