Here you go. This is the relative rotation. Set the Z value when setting the relative rotation. If you want absolute rotation, use the Z directly from the FindLookAtRotation node.
Source Actor is the wolf. Target Actor is the ThreatActor
Note that I made this work on the XY plane. If you want arbitrary rotations, that can be done, but it’s not a simple angle. You can use the FindLook at Rotation.
