Essential Buffing Questions (3.5/pf)

[Yeturs]

My question is this: If you were building a character based on buffing allies using Divine magic, what spells would you consider absolutely vital to the role? What spells are kinda nice to have, but most likely wand status?

I'm just looking for key-point spells, not necessarily on the same list, so throw druid cleric whatever spells my way please! I've never used buffing as a tactic. Thanks!

Mass Lesser Vigor, Prayer, and Recitation are all good spells for persisted party buffing.

But for a dedicated buffer, you probably want War Weaver, which means arcane casting.

Mass Conviction is pretty sweet.

Early on you get Bless, and later magic circle against...

I like Elation, even if the duration is short it gives all a little boost.
Enlarge person can be useful throughout the entire game.
Remove fear

Blessing of Fervor (http://www.d20pfsrd.com/magic/all-spells/b/blessing-of-fervor) is a favorite. Prayer is as good as a luckstone for everybody during a fight.
