Stinging Rebuke (Aristocrat): Your quick wit and sharp tongue, not to mention your general demeanour allow you to attack causing mental stress in situations that would normally preclude this action, e.g. where language barriers exist or amidst the chaos of the battlefield.
This stunt costs a fate point to use and lasts for one whole scene or conflict.
There you go, a Christmas present of sorts for the rogues out there. On a similar note, for Dungeon Masters looking to turn up the heat on mages it is worth remodelling this stunt in order to outfit monsters and foes who specialise in haranguing magic-users on the battlefield, e.g. a pack of goblins with the Magehunter stunt.
Wearing down a mage’s mental stress track can be an especially nasty tactic considering that many sorcerers and mystics depend on it as a resource when casting spells. In fact, as mentioned previously it’s worth looking at ways to present mental stress to players as part of the toils of adventuring in order to reign in magical powers. Accepting stress is a valid interpretation of a minor cost. For more examples of how mental stress can come about as a by-product of adventuring see the rules on Insanity in the Freeport Companion.
