Khelgar Ironfist

Khelgar Ironfist (male neutral good dwarf fighter) is a joinable NPC in Neverwinter Nights 2.

"Khelgar is a good-natured dwarf with a love of the finer things in life. He's strong and tough, even by dwarf standards, and developed a fearsome reputation as a brawler. Khelgar is heading to the city of Neverwinter, to find a monastic order that has opened their doors to anyone who wishes to learn. Khelgar is going to make them rue that policy quickly."

Gameplay
Khelgars stats are simply optimal for a defensive frontline fighter (Str 18, Dex 13, Con 18, Int 10, Wis 10, Cha 7, at Level 4, Pointbuy 33 for Str 17 at level 1), but not that well for a monk.

Spoilers
Spoiler warning: Plot and/or ending details follow.

If you complete his side quests, you will be given the option of turning him into a monk or keep him as a fighter. When converted to a monk, he retains all his current ability scores but is reverted back to level 1 with enough experience points to immediately leveling him back to the current level. His alignment also changes to lawful good and his patron deity changes to Tyr.
