Maximum caster level

Maximum Caster Level
Some 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 level exceeding the MCL or caster level increasing effects pushing the caster level of the spell past the MCL.

The following spell effects are not affected by maximum caster level - they will scale forever with increases in caster level:
 * The duration of spells is never limited by maximum caster level.
 * Spell damage absorption amount (like Protection from Energy or Stoneskin) is never limited by maximum caster level.

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).

Increasing Maximum Caster Level
There are a select few effects that can increase the maximum caster level of spells. However, a few spells are (probably incorrectly) not affected by MCL increasing effects.
 * Sorcerer Air / Earth / Fire / Water PRE enhancements: +1 MCL to element type per tier, total of +3
 * Tower of Despair Sorcerer Air / Earth / Fire / Water PRE sets: +2 MCL to element type if Savant III (stacks with savant MCL increase)

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.
