# Abilities
Abilities have 3 basic ways to determine when it is time to cast an effect:
1. Event based abilities are triggered by events in animations, and can be triggered multiple times by the same animation if that animation has multiple events configured.
2. Instant abilities cast their effect right away, and in the cast of channeled abilities, instantly on each tick of the channel.
3. Complete abilities cannot cast their effect until a cast reaches the end of its cast timer and completes successfully.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.anyrpg.org/architecture/ability-system/abilities.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
