Thief (Disgaea)

The Thief is a Humanoid class in Disgaea: Hour of Darkness.

Overview
The Thief is a support class specialized in stealing, helping the party by getting rare items or disarming the enemy. They're not suited for direct combat as their stats and weapon proficiencies are overall terrible, with Guns being their best option.

Passive skill: This class uses an improved stealing formula, and has a higher maximum steal chance.

Note that in Disgaea 1 Complete they are replaced by their female counterparts, though the change is purely visual and they function the exact same way.

Quotes
"Stealing is officially recognized as an advanced technique. The Thieves' Guild is the largest organization of the Netherworld. Thieves will steal anything by request, and anyone can join the Thieves' Guild as long as they have the skill. The most legendary of them all is known as the "King of Thieves.""
