I have a sorceress/bard/druid who is now Sor 1/Brd 5/Drd 4. This means, she has wild shape. But she does not have Natural Spell. Her feats currently are: Dodge, Mobility, Practiced Spellcaster, Great Fortitude, and Spell Focus (Enchantment).
For next level, it would make sense to take Natural Spell so that she can cast spells while in wildshape form. But, I am thinking it would also be useful to take Leadership and have a cohort and a team of loyal followers. Maybe even worth giving up the ability to cast 1st and 2nd level spells without returning to human form.
I am thinking that it would be really useful to have an Oracle for a cohort. Not only do they have healing abilities (and more spells), but also more healing, thus freeing up the cleric and saving money on healing potions. The main reason for wanting an oracle cohort, is to gain divinatory ability.
Thoughts?
I would only take natural spell if I plan to use the wildshape. As of now it seem that wildshape is not a priority for you so leadership may be the better choice.
