Cast A Spell

Most spells require 1 standard action to cast. You can cast such a spell either before or after you take a move action.

Note: You retain your Dexterity bonus to AC while casting.

Spell Components

To cast a spell with a verbal (V) component, your character must speak in a firm voice. If you're gagged or in the area of a silence spell, you can't cast such a spell. A spellcaster who has been deafened has a 20% chance to spoil any spell he tries to cast if that spell has a verbal component.

To cast a spell with a somatic (S) component, you must gesture freely with at least one hand. You can't cast a spell of this type while bound, grappling, or with both your hands full or occupied.

To cast a spell with a material (M), focus (F), or divine focus (DF) component, you have to have the proper materials, as described by the spell. Unless these components are elaborate, preparing them is a free action. For material components and focuses whose costs are not listed in the spell description, you can assume that you have them if you have your spell component pouch.


You must concentrate to cast a spell. If you can't concentrate, you can't cast a spell. If you start casting a spell but something interferes with your concentration, you must make a concentration check or lose the spell. The check's DC depends on what is threatening your concentration (see Magic). If you fail, the spell fizzles with no effect. If you prepare spells, it is lost from preparation. If you cast at will, it counts against your daily limit of spells even though you did not cast it successfully.

Concentrating to Maintain a Spell: Some spells require continued concentration to keep them going. Concentrating to maintain a spell is a standard action that doesn't provoke an attack of opportunity. Anything that could break your concentration when casting a spell can keep you from concentrating to maintain a spell. If your concentration breaks, the spell ends.

Casting Time

Most spells have a casting time of 1 standard action. A spell cast in this manner immediately takes effect.

A spell that takes 1 round to cast is a full-round action. It comes into effect just before the beginning of your turn in the round after you began casting the spell. You then act normally after the spell is completed.

A spell that takes 1 minute to cast comes into effect just before your turn 1 minute later (and for each of those 10 rounds, you are casting a spell as a full-round action, just as noted above for 1-round casting times). These actions must be consecutive and uninterrupted, or the spell automatically fails.

When you begin a spell that takes 1 round or longer to cast, you must continue the concentration from the current round to just before your turn in the next round (at least). If you lose concentration before the casting is complete, you lose the spell.

A spell with a casting time of 1 swift action doesn't count against your normal limit of one spell per round. However, you may cast such a spell only once per round. Casting a spell with a casting time of 1 swift actiondoesn't provoke attacks of opportunity.

You make all pertinent decisions about a spell (range, target, area, effect, version, and so forth) when the spell comes into effect.

Attacks of Opportunity

Generally, if you cast a spell, you provoke attacks of opportunity from threatening enemies. If you take damage from an attack of opportunity, you must make a concentration check (DC 10 + points of damage taken + the spell's level) or lose the spell. Spells that require only a free action to cast don't provoke attacks of opportunity.
Casting on the Defensive

Casting a spell while on the defensive does not provoke an attack of opportunity. It does, however, require a concentration check (DC 15 + double the spell's level) to successfully cast the spell. Failure means that you lose the spell.

Touch Spells in Combat

Many spells have a range of touch. To use these spells, you cast the spell and then touch the subject. In the same round that you cast the spell, you may also touch (or attempt to touch) as a free action. You may take your move before casting the spell, after touching the target, or between casting the spell and touching the target. You can automatically touch one friend or use the spell on yourself, but to touch an opponent, you must succeed on an attack roll.

Touch Attacks: Touching an opponent with a touch spell is considered to be an armed attack and therefore does not provoke attacks of opportunity. The act of casting a spell, however, does provoke an attack of opportunity. Touch attacks come in two types: melee touch attacks and ranged touch attacks. You can score critical hits with either type of attack as long as the spell deals damage. Your opponent's AC against a touch attack does not include any armor bonus, shield bonus, or natural armor bonus. His size modifier, Dexterity modifier, and deflection bonus (if any) all apply normally.

Holding the Charge: If you don't discharge the spell in the round when you cast the spell, you can hold the charge indefinitely. You can continue to make touch attacks round after round. If you touch anything or anyone while holding a charge, even unintentionally, the spell discharges. If you cast another spell, the touch spell dissipates. You can touch one friend as a standard action or up to six friends as a full-round action.

Alternatively, you may make a normal unarmed attack (or an attack with a natural weapon) while holding a charge. In this case, you aren't considered armed and you provoke attacks of opportunity as normal for the attack. If your unarmed attack or natural weapon attack normally doesn't provoke attacks of opportunity, neither does this attack. If the attack hits, you deal normal damage for your unarmed attack or natural weapon and the spell discharges. If the attack misses, you are still holding the charge. (here for reference we dont use it)

Ranged Touch Spells in Combat: Some spells allow you to make a ranged touch attack as part of the casting of the spell. These attacks are made as part of the spell and do not require a separate action. Ranged touch attacks provoke an attack of opportunity, even if the spell that causes the attacks was cast defensively. Unless otherwise noted, ranged touch attacks cannot be held until a later turn information.)


When you cast a spell that allows you to make a ranged touch attack (such as scorching ray), and an enemy is within reach, do you provoke two attacks of opportunity?

Yes, you provoke two attacks of opportunity: one for casting the spell and one for making a ranged attack, since these are two separate events. (Note that at spell that fires multiple simultaneous rays, such as scorching ray, only provokes one AOO for making the ranged attack instead of one AOO for each ranged attack. It still provokes for casting the spell.
