Trickster's Unstable Presence

You now crit on both 19 and 20s.with finesse weapons

Upon killing or critically striking a target with a finesse weapon attack you MUST blink up to 20 feet to an unoccupied square within sight and make a DC15 acrobatics check. If you succeed you can make an attack action as a free action. if you fail you do not get to make an attack and also provoke an attack of opportunity from all creatures in range (including ranged creatures and spellcasters, giving them a free action to attack or cast a spell). This action must be targeted towards you.

The Blink can occur up to 6 times in a turn but you roll disadvantage on your acrobatics check after the 2nd blink.
