I would like to make a comparison between 3.0 and 3.5 regarding to this question. Let's start only with Wizard/Sorcerer spells... Persistent Spell is a metamagic feat that changes a spell with duration other than instantaneous or permanent into a spell with duration of 24 hours. You need to already have the Extend Spell feat as a requisite, so in a way PS is a second-level feat of a chain so it's ok for me to be better than others.
In 3.0 Persistent Spell costs +4 level increase, and in my opinion this used to be a fair price, however some spells (the ones which are powerful but balanced with a very short duration) are really good to be persistent-ed:
Resistance: +1 to all ST, costs a 4th slot
Detect Magic: still needs concentration for more info, costs a 4th slot
Shield: +7 AC (one side) and +3 reflex, costs a 5th slot
Detect Secret Doors: still needs concentration for more info, costs a 5th slot
Detect Thoughts: works as detect-sentient-creature or concentrate to read thought, costs a 6th slot
Lesser choices but still good could be Message (4th), Protection from Evil (5th), Detect Undead (5th)... These seemed to me quite good uses of the feat, but not game breaking, except maybe Shield. What do you think? Other spells to suggest?
In 3.5 it's very different, because the cost of +6 slot actually doesn't make it seem worth for any spell, it would have been maybe worth for Shield but the spell is changed to +4 AC only, and it's definitely not worth a 7th slot! Is there ANY use of Persistent spell for an arcane caster in 3.5?
