Suggestions for Preferred Spell?

[Nemal]

I have an Evil cleric with the Undead, Dragon, and Fate domains (he has the third one for plot reasons, 100% homebrew), and I'm considering taking Preferred Spell for his level 9 feat.

What would be a good choice of spell for him? My first instinct is Enervation (from the Undead domain), as it's an excellent spell to be able to use over and over, but I was wondering if there's a better alternative I'm missing.

Cure light wounds - as an evil cleric you still may want to patch you up or pretend you are a good cleric ;-)
Or a cool domain spell for which you then can use your normal slots.

Cure light is the kind of spell I'm always carrying around in wands, so probably not the best choice.

Cure Critical might be a better choice, but, well, the whole party is built around the assumption that I'm not going to be healing (much), and I'd hate to spoil my party with more than a couple rounds of healing per fight :p

Do you get dragon breath spell with the dragon domain?
That would be a great one.
Otherwise think of one you can make the most of spontaneous casting, e.g metamagic feats.

Yeah, the character has Dragon's Breath as a spell.

Taking that one would mean that the character could nuke fairly competitively with the sorcerer for a while... I'll consider it.

Thanks! :)
