Maximum caster level

Maximum caster level
Many spells are subject to a maximum caster level (MCL). The part of the spell that scales by caster level will no longer scale when the maximum caster level is reached or exceeded, whether through the character's caster level exceeding the MCL or caster level increasing effects pushing the caster level of the spell past the MCL.

It's important to distinguish spell level from caster level and caster level from maximum caster level.

Some general notes:
 * The duration of spells is usually not limited by a maximum caster level.
 * Some damage absorption spells have a maximum caster level (Protection from Energy / Elements), and some do not (Stoneskin).
 * Certain spells add the caster level to a roll, which is different than a standard save DC. Some have a maximum caster level (Dispel Magic, Greater Dispel Magic) and some do not (Knock, Mordenkainen's Disjunction).

Maximum caster level is sometimes displayed in spell description. If you have effects that increase your max CL (see below), the description is not updated; game does not display this information anywhere.

Increasing maximum caster level
A few effects can increase the maximum caster level of spells (and SLAs).

 * Artificer Renegade Mastermaker tier 5 ability Mastermaker: no cap for Repair spells

A few spells are (probably incorrectly) not affected by MCL increasing effects - notably Eladar's Electric Surge and Niac's Biting Cold, forever stuck at MCL 20.

Sorcerer/Wizard spells with maximum caster level
Only spells that are limited in some part to a maximum caster level (most commonly spell damage) are listed, unless the absence of a MCL is notable.

Cleric/Favored Soul spells with maximum caster level
Only spells that are limited in some part to a maximum caster level (most commonly spell damage) are listed, unless the absence of a MCL is notable.

Only spells not on the Sorcerer/Wizard list are listed, as spells shared with the Sorcerer/Wizard count as "Arcane" when cast by Clerics/Favored Souls, notably for effects like Arcane Augmentation.
