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). 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 invocations, gestures, and concentration from one round to just before your turn in the next round (at least). If you lose concentration after starting the spell and before it is complete, you lose the spell.
You only provoke attacks of opportunity when you begin casting a spell, even though you might continue casting for at least one full round. While casting a spell, you don’t threaten any squares around you.
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.
- 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 materials are elaborate preparing these materials is a free action. For material components and focuses whose costs are not listed, you can assume that you have them if you have your spell component pouch.
Concentration: 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 the Concentration skill). 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.
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 + spell 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 + spell level) to pull off. 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, either in the same round or any time later. In the same round that you cast the spell, you may also touch (or attempt to touch) the target. 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. However, the act of casting a spell 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. 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 discharge of the spell (hold the charge) indefinitely. You can continue to make touch attacks round after round. You can touch one friend as a standard action or up to six friends as a full-round action. If you touch anything or anyone while holding a charge, even unintentionally, the spell discharges. If you cast another spell, the touch spell dissipates.
Dismiss a Spell: Dismissing an active spell is a standard action that doesn’t provoke attacks of opportunity.
Activate Magic Item
Many magic items don’t need to be activated. However, certain magic items need to be activated, especially potions, scrolls, wands, rods, and staffs. Activating a magic item is a standard action (unless the item description indicates otherwise).
- Spell Completion Items: Activating a spell completion item is the equivalent of casting a spell. It requires concentration and provokes attacks of opportunity. You lose the spell if your concentration is broken, and you can attempt to activate the item while on the defensive, as with casting a spell.
- Spell Trigger, Command Word, or Use-Activated Items: Activating any of these kinds of items does not require concentration and does not provoke attacks of opportunity.
Use Special Ability
Using a special ability is usually a standard action, but whether it is a standard action, a full-round action, or not an action at all is defined by the ability.
- Spell-Like Abilities: Using a spell-like ability works like casting a spell in that it requires concentration and provokes attacks of opportunity. Spell-like abilities can be disrupted. If your concentration is broken, the attempt to use the ability fails, but the attempt counts as if you had used the ability. The casting time of a spell-like ability is 1 standard action, unless the ability description notes otherwise.
Using a Spell-Like Ability on the Defensive: You may attempt to use a spell-like ability on the defensive, just as with casting a spell. If the Concentration check (DC 15 + spell level) fails, you can’t use the ability, but the attempt counts as if you had used the ability. - Supernatural Abilities: Using a supernatural ability is usually a standard action (unless defined otherwise by the ability’s description). Its use cannot be disrupted, does not require concentration, and does not provoke attacks of opportunity.
- Extraordinary Abilities: Using an extraordinary ability is usually not an action because most extraordinary abilities automatically happen in a reactive fashion. Those extraordinary abilities that are actions are usually standard actions that cannot be disrupted, do not require concentration, and do not provoke attacks of opportunity.
Use Special Ability (Feat)
Certain feats let you take special actions in combat. Other feats do not require actions themselves, but they give you a bonus when attempting something you can already do. Some feats are not meant to be used within the framework of combat. The individual feat descriptions tell you what you need to know about them.
Use Mundane Ability (Skill)
Most skill uses are standard actions, but some might be move actions, full-round actions, free actions, or something else entirely. The individual skill descriptions tell you what sorts of actions are required to perform skills.
