Blink Strike

You flourish your weapon, and vanish in a flash of silver. Choose a creature that you can see within 30 feet of you. You then teleport to an unoccupied space next to them, afterwards making a melee weapon attack against them with advantage. If you land the attack, you may repeat this process, without advantage, for however many attacks you have remaining. Missing any attack in the attack sequence ends the spell early, causing you to lose any additional attacks you may have had remaining.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the amount of attacks you can pull off increases by 1 for each spell slot above 1st. However, for each spell slot above 1st, you gain a cumulative -2 to attack rolls made via casting this spell.
