How fortunate! I happen to be playing a druid for the first time and he has just reached 6th level. I'm very happy with how he's turning out. So here is how I've put him together:
Attributes
Highest score in Wisdom, of course, followed by Dexterity, Constitution, Strength, Charisma, Intelligence.
Skills
Maxed-out: Concentration, Spellcraft
Five ranks: Heal, Handle Animal, Know (Nature), Ride, Survival
Some points: Diplomacy
Feats
Spell Focus (Conjuration), Augment Summoning, Combat Casting, Natural Spell
I'm in a mostly outdoor equestrian campaign so my animal companion is my horse.
Tricks
Attack, Defend, Come, Fetch
Feats
Endurance (mandatory), Run (mandatory), Improved Natural Attack (Hoof)
My preferred wild shape is that of a leopard. The best way to evaluate a good wild shape is to add the creature's Str, Dex and Con together and compare to other medium-sized creatures. Also the pounce attack of a leopard is the most devastating full-round attack of any medium sized natural animal.
The ideal animal to summon, with augment summoning, is a Hippogriff; D3 hippogriffs are always superior to one of any SNA III creature.
If shameless power-gaming is involved in your campaign (it isn't in mine), instead of playing a Druid 6, play a Monk 1/Druid 5. Your armour class will be fabulous.
