Cyphers
Cyphers are one-use abilities that your character has. They change from session to session, and you'll always be getting more of them, so use them when you need them (don't hoard them). A cypher might be a bit of luck that helps you out, a moment of inspiration about the answer to a problem, or a surge of adrenaline that pushes you beyond your normal limits. The GM will tell you what cyphers you have and will decide when you get replacements for the ones you've used.
Although most cyphers are not physical objects, in a fantasy game, a magic scroll or potion is a cypher. In a space opera game, a mysterious alien gizmo is a cypher.
You can have up to two cyphers at one time; this is your cypher limit.
Your character type might allow you to have additional cyphers at the same time.
