# Games : D&D 3.5 : Rules : Actions & Abilities
## Abilities
Magical effects come in two types: Supernatural and Spell-Like.
Additionally, members of certain classes and certain creatures can use special abilities that aren’t magical. These abilities are called Extraordinary or Natural.
```

Natural A non-magical ability. Examples: walking, swimming (for aquatic creatures), flight (for winged creatures)
Natural abilities are those not otherwise designated as Extraordinary, Supernatural, or Spell-Like.
Usually not an action because most automatically happen in a reactive fashion.
Those that are actions are usually std, cannot be disrupted, do not require concentration, and do not provoke AoOs.
