The default Stunt for Gnomes is Tiny (see below). Most gnomes also favor either Gnome Prankster or Gnome Assassin.
While many of these Stunts are not wholly specific to Gnomes, the gnomish affinity for illusion and invisibility works as a better justification for tricks like Ninja Vanish than any other character type.
Tiny (Athletics/Stealth Stunt; requires Gnome or Halfling or Child) – You gain a +1 bonus when using Athletics or Stealth to hide behind any sort of cover or move through small spaces.
Gnome Prankster (Burglary Stunt; requires Gnome) – When you use Burglary to create an advantage, you gain an additional free invoke on the aspect you create or exploit.
Gnomish Sneak Attack (Stealth Stunt; requires Gnome) – When you use Stealth to create a boost or advantage, you gain an additional free invoke on the aspect you create or exploit.
Fade Out (Stealth Stunt; requires Gnome or Illusion) – You can use Stealth to hide even when you’re out in the open and wouldn’t normally be able to justify it. However, as soon as you move, you become visible again, unless another stunt you have states otherwise. This counts as illusion magic.
Walk Unseen (Stealth Stunt; requires In Fade Out) – When you are concealed using Fade Out, you may move one zone per exchange without becoming visible. If there is an aspect in play that would normally justify the use of Stealth to hide yourself, you may pay a fate point to be able to make an overcome action with Athletics without becoming visible. This counts as illusion magic.
Striking at Shadows (Stealth Stunt; requires Walk Unseen) — Once per scene, when you successfully defend against an area attack with Athletics, you may roll Stealth to hide as a free action. This count as illusion magic.
Fade Away (Stealth Stunt; requires Fade Out) — At the cost of a fate point, you may immediately exit a scene, vanishing from all senses and escaping. This counts as illusion magic.
Deceptive Veil (Deceive Stunt; requires Gnome or Illusion) — You can disguise yourself as a person of different gender, height, skin tone, or age, using detailed illusions. This works identically to using Deceive to disguise yourself, but requires no special tools and counts as illusion magic.
Instant Veil (Deceive Stunt; requires Deceptive Veil) — You can use Deceptive Veil without any time to prepare, in nearly any situation.
Gnome Assassin (Stealth Stunt) — When you can surprise an enemy or attack from concealment, you can attack with Stealth. If you succeed on that attack, you also create a boost related to your continued concealment. If you succeed with style, you add an additional free invoke to that boost.
Murder Spree (Stealth Stunt; requires Gnome Assassin) — When you use Gnome Assassin, you can attack multiple targets within a zone, dividing your shifts between targets, even if those targets are not a mob of nameless NPCs.
Gnome Sniper (Stealth Stunt; requires Gnome Assassin) — When you use Gnome Assassin with a ranged weapon, you can attack targets up to two zones away, and you create a full situation aspect instead of a boost. On a tied attack, you still create a boost.
The Quiet Knife (Stealth Stunt; requires requires Gnome Assassin) — When you use Gnome Assassin you create a full situation aspect as per create an advantage instead of a boost. When you tie, you still get a boost as per normal.
Lurking Dread (Stealth Stunt, requires the Illusion skill at least at Fair and Fade Out) — When you roll Stealth for In Fade Out, you can also create an illusion aspect, Lurking Dread, with a free invoke, and if you succeed with style, you gain an additional free invoke. This aspect remains for as long as you are hidden, until you abandon it, or until you expend all of your free invokes on the aspect. Even as your position becomes more difficult to pinpoint, the sensation of your presence becomes more pronounced and oppressive, crowding on others in the scene, as if you were constantly just over their shoulders or underfoot or just out of the corner of their eyes. While this aspect persists, you can make mental attacks to provoke fear using Stealth instead of Provoke, remaining hidden as you do so. Such an attack can be resisted with Will normally, or with Notice. An enemy who succeeds on a Notice defense pinpoints your position, ending the Aspect.
