Agreed, I was throwing together ideas in a hurry, and did some silly things.
1. I want Warlock abilities.
2. I want to be first and foremost a Cleric of Shar, but I don't much like advancing as a Cleric so would rather do it through prestige classes.
3. The above 2 interact well based on the idea of Shadows, and I really liked the ritual involving running around in Shadows taking Con damage.
4. One way to get around Con damage is Sacred Vitality. I'm a Cleric. I should have this.
5. Damn, I'm an evil cleric, I don't think I can have Sacred Vitality, I must find a work around.
6. Haha, Eberron action points. Heroic Channelling. Damn, I'm not playing in an Eberron campaign, our DM took away our automatically gaining action points at 5th level, and now occassionally awards them as karma. At least he's not against the idea.
7. Rages and Frenzies can get you a free action point through Raging Luck! Damn, when raging you can't use actions like the Supernatural Ability to Turn Undead, of Heroically Channel your way to a minute's ability damage immunity.
8. Sorcerers related to angry angry White Dragons via 2 feats can!
9. (And this is where it gets very silly) If you have 3 ranks in Sorcerer anyway, you may as well advance it once more, and get yourself Ascetic Mage so you can use those silly spells to actually hit something from time to time.
If we take back Step 9. Get rid of the monk level, forget advancing Sorcerer beyond 3, forget Ascetic Mage, and just concentrate on being the best Cleric of Shar Hellfire Warlock with sorcerer raging for free lucky ability to be immune to ability damage? Is it still a stupid idea? 3 Levels and 5 feats for an ability damage workaround. Probably not worth it?
