Dannyalcatraz said:I'll second Natural Spell- but you can hold off on that until you can actually wildshape, so leave that for 3rd level. If you wait until 6th level, it might be too late.

One other hint for the core druid: unlike the wizard's familiar and the paladin's mount, your animal companion doesn't cost you anything but your time if you lose it & need to replace it. So in making tactical plans, don't give too much weight to keeping it alive--you probably won't succeed anyway, so you're just wasting energy being overcautious. It's a once-per-adventure Summon Nature's Ally with unlimited duration; treat it as such.
