General Stuff
You generally start with two Abilities, but talk to your GM during character creation, obviously.
Note that you can only use one ability that adds a 1d to an Action Roll at a time, even if both seem to apply. It's also pretty strongly recommended that you don't take those until after you filled in the ability with three dots, all of those are pretty situational and deliberately designed to have downsides. They aren't really a good way to get an extra dice unless that's where you want your character to go.
Other things can stack, like 'Pushing Yourself takes one less Stress', but that can't result in negative Stress, just zero.
When something says you can do it 'once per episode per dot you have in [action]', that is before any adding or subtracting dice at all. It's the literal number of dots on your character sheet. And there is no minimum there, if you have no dots, you can't use that ability. So...you probably don't want to take it.
[This page is a work in progress, in that I keep writing new abilities.]
Add a dice
Apophenic
You can always always always find connections between things, no matter how slight or literally nonexistent.
1d to Understand whenever you want. And when you do this, a Failure is treated as a Partial Success, giving you some true connections. However, on a Partial Success, you also will get false connections that your brain just made up. Even if you Push Yourself to Full Success, while you will get more real connections, you still do not know which ones you just invented from thin air.
No Plans, No Prototype, No Backup
You're good at jerry-rigging something that will work. Once.
1d to Modify if you're using some sort of technology that was specially designed in advance for the task at hand, which you can do in a flashback. However, if you fail, it breaks and you not only lose that 1d, but lose an additional 1d in trying again.
Kevin Bacon
You always know someone who knows someone who knows someone who knows someone who knows this person.
1d to Connect if you're using either your real identity or a long-standing alias and have spent some time doing research on this person, which can be done in a flashback. However, using this information does mean things can be traced back to you or that alias, and the GM might add an Outcome for that.
Bavarian Fire Drill
Sometimes sheer panic is the best solution.
1d to Order if you rush up to a group without explanation or any obvious authority and bark out emergency orders to a group to make them panic and do something without thinking. You can be Assisted in that roll by a teammate without the teammate taking Stress if they pretend to challenge your authority, but are ultimately 'convinced'. However, if this fails, it tends to fail very badly, and people will likely attempt to alert the actual authorities
Fully In Character
When you commit to a character, you commit to the character.
1d to Grift when you are grifting as one of the characterizations you have an Aptitude in, in addition to the normal increased Effect. However, the GM can add an additional Outcome that you are temporarily unable to exit the character.
Sticky fingers
You can picketpocket without even paying attention.
1d to Grasp when pickpocketing if instead of trying to get anything specific, you take a random item from their pockets. Item will be determined by GM fiat or random roll. You can keep doing this until you get what you wanted, but once you use it one someone, you cannot stop using this and pickpocket that person normally.
Social
You have a tell
You're an expert in watching people's microexpressions and listening to the timber of their voice.
You can take one Stress to see right through another person for the episode. Once you do, if you are interacting with them or observing at close range, you can always tell if they are lying. If farther away or over comms, you have increased Effect in gathering information about whether or not they're lying.
The best lie is the truth
Even when you're telling the truth, you're lying.
Whenever you are attempting to mislead people, Pushing Yourself takes one less Stress if what you are saying is technically mostly truthful, just misleading.
Background player
No one ever seems to remember what you look like unless you make an impression.
Whenever you interact with someone and appear to be someone unimportant, you can make an Action Roll to keep them from remembering you, and Pushing Yourself takes one less Stress. If you keep the interaction small enough, it might not even require a roll. On a full success, they will completely forget your face and will never compare that character to anyone they later meet.
A Thousand Faces
You know how clothes change perception. You have wigs. You know how to use makeup contouring.
Given just a few minutes to build an image, you can walk straight up to old friends and they won't recognize you. You might even be able to convince them with with just a Makeup Kit and a Wig. If they think they do recognize you, Pushing Yourself takes one less Stress.
Mind
Shoulder Surfing
The best way to figure out someone's password is to watch them type it.
You're an expert at positioning yourself or cameras to see someone type things into a computer or keypad, as long as you can get the line of sight you want, you don't have to roll to get passwords or keycodes. You can still be noticed, but Pushing Yourself to avoid that takes one less Stress.
Cut to me walking up to them
Whenever you need to find someone who isn't in hiding, you just do. You can do this once per episode per dot you have in Locate. Note you probably do not want to do this to people who are dangerous, because the premise is that the scene literally will just cut to you walking up to them.
I can buy us some time
You always know right before something bad is going to happen, and you're smart enough to delay it, or how to squeeze out a few more seconds.
Whenever the last segment of any clock should fill up, you can immediately take one Stress and do either an Understand or Locate Action Roll. On a Success or Partial Success, the last segment is temporarily delayed long enough to do just do one or two more things before the consequences actually happen. The last segment does eventually fill in, nothing you do can stop that. This can only be done once per clock.
Flashbacks
I had prep time
You do Batman levels of prep.
Whenever the Unpredictability is 1 or 2 for yours or someone else's Flashback, you can do a Mind-based Action Roll or gather information. On a Success, you reduce the Unpredictability by two, on a Partial Succes, by one. This doesn't reduce the Difficulty.
Offscreen moment of awesome
That was probably a really cool thing you did. Sadly, none of us saw it.
Whenever the Difficulty is 1 or 2 for your own Flashback, you can do a Resistance Roll of whatever Attribute the GM thinks is most relevant. On a Success, you reduce the Difficulty by two, on a Partial Success, by one.. This doesn't reduce the Unpredictability.
Noodle incident
Once per epeisode, you can do a flashback with absolutely no Stress and no rolls to get a reasonablely small result, like assistance on a roll. However, neither you, nor other players and not even the GM, can ever describe in full what happened in it.
All other players must choose to have their character either agree it is something that is best not spoken of except via extremely strange and context-less references to things that happened or, or alternately can they have absolutely no idea what happened or what people are even talking about. Characters who choose to never speak of it can pay one Stress in that episode to have done one additional inexplained thing in the incident.
Body
Put that away before you hurt yourself
If someone is holding a gun, and you take an action to remove the gun, you can take one Stress to keep from having to roll for success or to prevent anyone getting shot during that action. You still may have to roll for other outcomes, such as the gun going off randomly or them alerting others. You can do this once per episode per dot you have in Assault.
How long have they been there?
If you want to be in a room that you can get to, and it wouldn't cause any sort of narrative issue or paradox, you can retroactively already be in the room, without anyone there seeing you enter it. You do a Stealth Action Roll, and instead of the normal Success, Partial Success, or Failure, the result is instead are the max number of minutes you've been in the room. Additionally, if you then do nothing at all, you are assumed to be unnoticed for a few more minutes, until you have to start doing Stealth checks.
Where'd they go?
If no one nearby has reason to be watching you or trying to confine you, you can disappear into a vent or through a door even when it doesn't really make sense that you can vanish that quickly. You can do this once per episode per dot you have in Stealth.
I hang from buildings by my fingertips
Once you have something firmly in your hands, it is nearly impossible to disloge. Pushing Yourself to avoid losing hold of something you currently Grasp takes one less Stress. This applies to building ledges, climbing rope, guns, people...
No Sell
When you are attacked, you let them get a hit in for free and do not react at all, to show you mean business.
When you roll Assault in combat, and have Moderate or Severe Harm as an Outcome, and put a Partial or Full Success result die into avoiding it, you can then choose to deliberately take the full Harm anyway, and then immediately Shake It Off with just one Stress.
This will cause a lot of people who are watching, or even who hears about it, to not want to fight you.
General
Determinator
You can ignore any new Harm as long as you keep doing the same Action or the same general thing you were doing when you got the Harm. It only impacts you when you finish whatever thing you are doing.
Fake it till you make it
If you're making an Action Roll, and you have zero dots in it, but have at least one dot in another Action in that Attribute, you can take one Stress to pretend you have one dot instead and roll 1d.
Where were you hiding all those?
You have unlimited Small Items on your person. This is somehow never noticeable outside of a search.
Hammerspace
Pick a standard Large Item or talk to the DM about a different one, and declare where you are always hiding it on your person, stretching plausibility to the breaking point for it to be there. This is somehow never noticeable outside of a search.
Gathering Information
It's not paranoia if…wait, who told you I was paranoid?
Whenever you gather information, you will notice nothing anything that could vaguely present a threat to the team, even on a partial success.
Fluent in body language
Whenever you gather information using a Body action, you get an addition 1d.
Seen all the tricks
Whenever you gather information using Order, Grift, or Modify, you get an addition 1d.
I just read about that on Wikipedia
Whenever you attempt to gather information that would plausibly be public information, take a Stress to coincidentally have read up on that topic recently and thus have Knowledge in it. This Knowledge stays with you the entire episode, but then goes away at the end.
