So, it will be:

- A trap NP in form of a Buff that last one time for the activation turn.

- Cancel out enemy's NP should the user be targeted.

- Deal damage to the said enemy.

- Gain critical stars if the trap is triggered.

You should fix the information as soon as possible Mamoru. In the end, a extremely unique NP indeed.
