The posted Druid build needs more Druid imho. It reads off like a Commoner. So here is a sort of hybrid between the one and page one, my ideas, and the ride around with a sling one.
Huntsmen
Human Druid 1
ACFS: Deadly Hunter, Phynxkin Companion, Druid Domain.
Abilities: Str 10, Dex 14, Con 14, Int 10, Wis 18, Cha 8.
Feats: Greenbound Summoning, Track, Nightbringer Initiate, Primitive Caster, Shape Soulmeld(Kruthik Claws), Shape Soulmeld(Soulspark Familiar).
Skills: Profession (herbalist), Survival, Hide, Move, Listen.
Stuff: Favored Enemy(human), AC Bonus, Swift Tracker, Nature Sense, Wild Empathy.
WBL: 100gp, Spellcasting Service(cl3 divine substitution[summon domain], 60gp), mule (8gp), 22gp left for sling and such.
Pets
Phynxkin: 6HP, init +5, 40ft speed, AC 13, bite +2 (1d6+2) & 2 claws -3 (1d4+1), pounce, hide/move +4.
Soulspark Familiar: 13 HP, +5 init, 30ft flight, ac 14, +5 ranged touch (1d4+1).
Before embarking on this event, for several weeks he tries to make a DC 15 Profession (herbalist) check to gather plants for Primitive Caster. For the first three days of the battle Hunstmen has the Summon domain for +2 to his CL with SNA spells which gives him a total of CL4. Typically he stalks his target (+10 to hide/move, +12 to tracking humans) and tries to use the surprise round to cast a Greenbound animal if possible, which for the next four rounds will dominate combat. When the situation calls for it, he can befriend nearby animals, such as a bird to scout for him. He has a mule to allow for movement while summoning, his Soulspark Familiar makes a nice shoulder cannon when deployed (else it hides in a leather bag). And the Phynxkin runs interference as needed, typically it can be up to 80ft form it's target and still make a full attack which let's it follow it's master with some distance between them.
I could have sworn Survival can be used to make rudimentary traps (like snares and such), but I can't think of where I seen that or maybe it's just wishful thinking.
Note on DFA: 30ft line of breath is 50ft closer than the pet needs to rip him a new breathing hole. It's in range of the Soulspark's lasers, and let's face it. As long as the Druid has a 1st level spell slot left, Greenbound is his auto win trump card.
