Cast a Spell
The vast majority of spells require at least a standard action to cast, and sometimes more. Spells that take more than a round to cast require a full action each round until they are complete. For more information about how spells and magic work, see Chapter 10.

Casting a spell takes a significant amount of concentration, forcing you to lower your defenses briefly. When you cast a spell, it gives targets threatening you in melee a chance to make an attack of opportunity against you (see Attack of Opportunity on page 248), unless the spell specifies otherwise—normally only the case for a few spells with a range of touch. If this attack of opportunity hits and damages you, you fail to cast the spell and lose the spell slot. For more information about threatened squares, see page 255. Source Core Rulebook pg. 246 |
