Inquisitor

The Inquisitor is a class kit in Baldur's Gate 2: Shadows of Amn. It is one of three kits of the Paladin and is considered one of the best kits in the game.

Game Description
"The Inquisitor has dedicated his life to finding and eliminating practitioners of evil magic and defeating the forces of darkness, and his god has provided him with special abilities towards that end."

Advantages: Disadvantages: 
 * May use “Dispel Magic” ability once per day per 4 levels (starts at 1st level with one use): ability is used at speed factor 1 and acts twice his actual level.
 * May cast “True Sight” once per day per 4 levels (starts at 1st level with one use) 
 * Immune to Hold, and Charm spells.
 * May not use “lay on hands” ability.
 * May not cast priest spells.
 * May not turn undead. 

At first glance the Inquisitor seems to be a costly kit to choose due to not being able to cast spells or turn undead. However, this class is a spell caster’s worst nightmare as it is able to cast two powerful anti-spell abilities twice their actual level thus being able to disrupt any and all spells with relative ease depending where you aim. This means if an Inquisitor is level 8, the Dispel Magic ability work as if the character is level 16.
