Forget [two-actions] Focus 4

You force creatures to temporarily forget about the target. The target is invisible while within your quantum field, and memories of the target are temporarily erased or rewritten. This makes it undetected to all creatures.

The first time an enemy attempts to locate the target (such as by Seeking) or uses Recall Knowledge to recall information about the target, they take 8d8 mental damage with a basic Will save as they suffer painful migraines and mental static while trying to process information about the missing target. On a critical failure the enemy is also confused for 1 round.
