You can use a hand that's holding a weapon to perform the somatic component of this spell.

Utility Spell

• You teleport up to 30 ft. to an unoccupied space on the ground, use your normal attack action from that position (with multiple attacks if applicable), then you teleport to your original position.

• Your first attack on this turn has advantage.

At your GM's discretion, you might be able to use an action other than attacking if it's quick and doesn't require you to move from the position you teleport to.
