Divine Casters and Class-Defining Spells

I'm trying to nail down which spells are critical to each spellcasting class for the purpose of modding -- I don't want to give powerful options without also taking away options of roughly equal power.


My spell list varies with level -- at low level, Hold Person is solid gold, while at high level it's trash and Draw Upon Holy Might is the hot level 2 slot choice.

It also varies with alignment: Holy Smite is great, while Unholy Blight seems much less useful.


Which spells do you always pick?
Which spells are generally useless?

Thanks, -- N
