Character Build: Buffer/De-buffer

[Dannyalcatraz]

How about a bard?

Good buff/debuff spell selection as well as the bardic song class ability.

Lyric Thaumaturge PrCl from Complete Mage is really sweet too.

And since they wear light armor at least, it wouldn't be a bad mix with Marshall. Especially with that Cha-boosting aura.

 

[Set]

Wizard, war weaver PrC (HerBatt).

This is a great choice.

Taking Archivist, so that you can pick up Cleric and Druid 'buffs' as well as various buffing and debuffing Domain spells (and Paladin / Ranger spells, etc), could also be a route to take.
