Multiattack

Three Longsword attacks.

Longsword

Melee Weapon Attack: +8 to hit, 5 ft., one target, 8 (1d8+4) slashing damage or 9 (1d10+4) slashing damage if used with two hands + 13 (3d8) acid cold fire lightning necrotic radiant or thunder (see Planar Attunement).

Warping Whirlwind (Recharge 5-6)

Bends reality around it slicing nearby creatures with sword strikes from across the planes. Each creature within 10 ft. of the planes hunter must make a DC 16 Dex save taking 18 (4d8) slashing damage and 18 (4d8) acid cold fire lightning necrotic radiant or thunder (see Planar Attunement) on a failed save or half damage if made.

Planar Traveler (1/Day)

Can transport itself to a different plane of existence. This works like the plane shift spell except hunter can only affect itself and can't use this action to banish an unwilling creature to another plane.
