My wife is playing tones of Octopath Traveler. I saw a power that I think would be fun for Pathfinder

Vengeful Blade Two Actions Feat 8

Fighter

---

You focus upon another to make them pay. Choose a target within range of a weapon you are wielding. Until the end of your next turn, you may make an attack at that target after it make any attacks or casts any spells. This will allow you to make more than one reaction in this round, but only for this feat. The action that triggers any of these attacks finishes before your attack starts, and you do not incur a multi-attack penalty for any of these attacks.

Thoughts?
