The Distracting Behavior talent in Far Horizons calls for ranks in Cunning.

Does that mean the score in the Cunning Characteristic, or is that a misprint?

Make a 'move' action.

Subtract strain 'up to' your Cunning stat to affect X- amount of NPC's.

So if you have a cunning stat of 3, you can affect 3 NPC's, or if you just want to annoy a single person, spend 1 strain.

They now have a 'Threat' to any checks they make, 2x Threat if you have the Improved version

That's how I read it

Since it states Ranks and not Rating and the fact that the talent appears multiple times in the tree, I was thinking it was tied to the ranks in Distracting Behavior.

The ranks of the talent are used to increase its maximum range.

I think FFG should have the talent reworded for clarity, replacing "ranks in Cunning" with "Cunning score" or something along that line.

Thank you both, MKX & HappyDaze, for clearing this one up
