He'stan by Koetetsu

Tier 1

Oak Sage (Quest) - Nature's Spirit increases the health regeneration of nearby allied heroes by 10. Collecting regeneration globes increases the regeneration bonus by 1 up to 30.

Reward: After collecting 30 globes the oak sage also increases mana regeneration of nearby allies by 2.

Heart of the Wolverine (Quest) - Nature's Spirit increases the basic attack damage of nearby allies by 5. Every Minion killed near you grants an additional 0.2 Attack Damage, and Takedowns grant 0.5 Attack Damage, to a max of 25 damage.

Reward: Upon gaining 25 bonus attack damage, also increase nearby allies' ability power by 10%.

Spirit of Barbs [Trait] - Nature's Spirit grants a shield to nearby allied heroes equal to 5% of their maximum health. If this shield is broken, it releases a spray of barbs that damages nearby enemies equal to the shield amount. A unit cannot be shielded again within 15 seconds.

Tier 2

Carrion Vine [Q]: The creeper vine passively devours dying (<20% health) minions and heals the druid for 50 (+4%/level) health. Occurs once every 3 seconds.

Maul [W]: Your animal companions slow enemies they attack by 20% for 1.5 seconds and stuns them for 0.5 seconds every 3rd attack.

Lingering Essence [Trait]: When a spirit dies, allies in its aura benefit from it 5 seconds longer.

Tier 3

Dispersed Barrier [E]: Cyclone armor spreads 25% of the shield amount to allied heroes near the target.

Poison Spores [Q]: The area attacked by the creeper vine continues to poison enemies that enter the area for 3 seconds and also increases the area affected by 15% per second up to a 45% increase.

Dire Wolf [W]: Summons a Dire Wolf instead of a raven that can withstand 2 more attacks before being driven away, deals 40% more damage and lasts 2 seconds longer.

Tier 4 (See Heroic Abilities)

Tier 5

Raging Assault: Attacking the same target increases attack speed by 10% up to 40%. Wears off upon attacking another target.

Solar Creeper [Q]: The creeper vine passively devours dying (<20% health) minions and restores 20 mana to the druid.

Synergy: If the carrion vine talent was taken, both effects will stack and also restores half of the health and mana restored to allies under the aura of nature's spirit.

Wind Veil [E]: When Cyclone Armor lasts its full duration gain 3 charges of block that reduce basic attack damage from heroes by 50%. Can only hold up to 3 charges.

Tier 6

Dire Bear [W]: Summons a Dire Bear to attack your enemies. The bear has 1200 (+4%/level) health, deals 150 (+4%/level) damage and is only driven away when its health is depleted.

Synergy: If Dire Wolf was taken, Force of Nature gains a second charge that summons a Dire Wolf if the Dire Bear is active.

Incorporeal [Trait]: Spirits are now invulnerable but move 25% slower.

Wind Shear [E]: If Cyclone armor is destroyed send out a twister that targets the nearest enemy (prioritizing heroes).

Synergy: If dispersed barrier was taken, each shielded ally and enemy hit by your twisters reduces Cyclone Armor's cooldown by 2 seconds.
