[Question]
Can One Cast Another Spell while Concentring in Pathfinder?

As the term implies, Concentration allows you make your spell more effective by being in the state of mental preoccupation, enabling a stronger caster to harness energy from it. It raises questions like Can you cast another spell while concentrating; does this limitation have negative effects; can there’s an exception or not?

[Answer]

According bold statement by Player”s Handbook on page <strong>203</strong>,

**Concearning on a Spell**: Casting a spell requires a concentration. Each spell description states if takes a standard action to cast.
(You cannot cast a spell
**if you are concentrating on this spell**
)```

Plainly speaking, Concentration solely for maintaining magic spells - one spell. The term does not mean there can be others simultaneously, thus there the **rule stands**:  **only maintain concentration or focus on one thing at a time within your mental powers**. Another way of phrasing rules of this situation.

But how to make exceptions:
[Exceptions]
In few situations you may not think, "But wait..."
* You could **already be concentrating** before you choose a new spell.
    • Keep concentration from spell that cast and now have room now
* Or you might receive a spell, say **Invisibility** while in a cast
    • Then let's think; how, this works with no cast?
**Rules Clarifie**

Here a breakdown so the concept easier:

    already be Concentriated. **So the situation** isn't so difficult.
