Cleric/Rogue PrC, one that progresses SA and Casting

[AustontheGreat1]

So I'm looking for a prestige class that progresses Sneak Attack and Cleric Casting. The character is Lawful Evil who focuses on shadows and summoning, as well as ranged attacks with a dash of assassination (though I don't think I'm going to go assassin, it just doesn't seem worth it.). Race is tiefling. Ummm...I'll fill in any more details as needed.

Thanks in advance for any help.

Edit: Crap. Posted this in the wrong section. Someone should please move this to the roleplaying section. My apologies.

The giant's own. ^^

Thanks for the replay. I reposted this in the appropriate section and someone suggested that already. I plan to either home-brew one of my own, or just go with a slightly beefed Black Flame Zealot.

Edit: Actually, while I'm here, I don't suppose that the "Giant made any other classes? Could you provide a link of where to find some other stuff he's made?

Never knew that PrC by the Giant existed.

..but if you were to turn your Tiefling into a Drow, I would then suggest the Eye of Lolth PrC, as found in Drow of the Underdark.

Just sayin'...
