What if you don't want to be good at anything?

So a while ago I decided to catch up on my Appendix N and ordered this whopping Dying Earth anthology. I'm currently reading through The Eyes of the Overworld and I fucking love Cugel. He's the kind of bastard I always kind of want to play in an RPG, and like any real-life D&D player he picks up opportunities at the bat of an eyelash and drops them as quickly and destructively as possible once he realizes they're no good.

But what class is he? The other thing I love about him is the only thing he's really got is his wits and blind fortune. Like he's no wizard; his fighting tactics usually involve cowardice, distraction, and lies; he's no good at sneaking or he wouldn't be in this fucking mess to begin with; and the only god he'd worship is a good of money and wenches and he'd probably like steal its favourite dog and get cursed or something.

So I guess he's this class (for retroclones):

The Libertine

This bird is going to offer you something awesome. Then it's going to fuck you over, and you're going to ruin its life and peace the fuck out.

HD: d6
Prime Requisite: Wisdom
Attack progression: As thief
Saves: As halfling (if this game separates race and class... as halfling thief. Being a halfling libertine doesn't give you saves as a double halfling thief. Don't be a smartass.)
Level progression: As cleric
Weapons: As thief
Armour: Heavier-than-leather armour is not sexy and you wouldn't be caught dead it in.

Wits - I lifted this right out of DCC. You have a Luck score, the starting value of which is equal to your Wisdom score. You can dump any number of points of Luck to boost the result of any roll by that much. If you are boosting a damage roll, the amount of luck may not be higher that half of the die's maximum damage (eg. you may add up to 3 damage to a d6, 4 to a d8, etc.).

Whenever you get a full night's rest, you regain Luck equal to your level, up to its original value.

EDIT: If you are using a percentile resolution mechanic, a point of Luck should be worth about 5%. On a d6-based skill system, the DM might decide that 1 pip = 3 Luck.

Ok that was fun.

It is 1 AM I should be in bed.

Goodnight
