Thief, rogue, conman - they are all basically the same thing. You excel at stealth, lifting and stealing things, and getting into locked places. You might be noble in your pursuits but your skill-set causes others to find you hard to trust. Knives, daggers, and other small weapons that you can easily conceal are your tools of the trade and you can move around in light armor as if you were never even there. Don't try to wear heavy armor though and stay clear of the heavy great sword.

The classic thief. This is a profession about speed and stealth, and taking what is rightly yours. This profession also covers Rogues and Assassins. Basically anyone that would do their work in the shadows, whether their work be for good or for ill.

Starting Bonuses and Penalties

You already know that playing as a thief grants you a salary of 80 shillings per week, though we won't say what nefarious method you used to obtain a weekly salary. You also already know that you get 60 character points at character creation and that you have a fence in each city that you can sell stolen goods to. Basically you are part of the thieves guild, an elaborate yet secret organization of stealthy professionals, for simply being a part of the thief profession. However these are not the only benefits a thief receives.

Effects on Weapon Usage

Thieves are best suited for small, light weapons. Daggers are the weapons that they are best at, which they have +10 to Melee Power when wielding them. They do not handle large weapons, heavy weapons, or noisy weapons well.

Effects on Armor Usage

Thieves are unable to wear heavy armor. They must stick with light armor. For a thief to wear other armor, the thief will need that armor's proficiency skill, however even with that skill the thief would suffer a -2 to Initiative per armor piece that is not light, and skills that keep you undetected will by 25% less effective over all.
