Editing Unwritten: System Reference Document/Aspects and Fate Points (section)

==Invoking Aspects==

The primary way you’re going to use aspects in a game of Unwritten is to invoke them. If you’re in a situation where an aspect is beneficial to your character somehow, you can invoke it.

In order to invoke an aspect, explain why the aspect is relevant, spend a fate point, and you can choose one of these benefits:

* Shift the result of your current roll by +2 after you’ve rolled the dice.
* Reroll all your dice.
* Pass a +2 benefit to another character’s roll, if it’s reasonable that the aspect you’re invoking would be able to help.
* Create an obstacle worth passive opposition of Fair (+2) that represents a complication caused by the aspect. 
* Add +2 to any source of passive opposition, if it’s reasonable that the aspect you’re invoking could contribute to making things more difficult. 

It doesn’t matter when you invoke the aspect, but usually it’s best to wait until after you’ve rolled the dice to see if you’re going to need the benefit. You can invoke multiple aspects on a single roll, but you cannot invoke the same aspect multiple times on a single roll. So if your reroll doesn’t help you enough, you’ll have to pick another aspect (and spend another fate point) for a second reroll or that +2.

The group has to buy into the relevance of a particular aspect when you invoke it; GMs, you’re the final arbiter on this one. The use of an aspect should make sense, or you should be able to creatively narrate your way into ensuring it makes sense.

Precisely how you do this is up to you. Sometimes, it makes so much sense to use a particular aspect that you can just hold up the fate point and name it. Or you might need to embellish your character’s action a little more so that everyone understands where you’re coming from. (That’s why we recommend making sure that you’re on the same page with the group as to what each of your aspects means—it makes it easier to justify bringing it into play.)

If the aspect you invoke is on someone else’s character sheet, including situation aspects attached to them, you give them the fate point you spent. They don’t actually get to use it until after the end of the scene, though.

===Free Invocations===

You don’t always have to pay a fate point to invoke an aspect—sometimes it’s free.

When you succeed at creating an advantage, you “stick” a free invocation onto an aspect. If you excel on the action, you get two invocations. Some of the other actions also give you free boosts. You also get to stick a free invocation on any consequences you inflict in a conflict.

Free invocations work like normal ones except in two ways: no fate points are exchanged, and you can stack them with a normal invocation for a better bonus. So you can use a free invocation and pay a fate point on the same aspect to get a +4 bonus instead of a +2, two rerolls instead of one, or you can add +4 to another character’s roll or increase passive opposition by +4. Or you could split the benefits, getting a reroll and a +2 bonus. You can also stack multiple free invocations together.

After you’ve used your free invocation, if the aspect in question is still around, you can keep invoking it by spending fate points.

If you want, you can pass your free invocation to another character. That allows you to get some teamwork going between you and a buddy. This is really useful in a conflict if you want to set someone up for a big finish—have everyone create an advantage and pass their free invocations onto one person, then that person stacks all of them up at once for a huge bonus.
