I was thinking in include a leader build and a controller one.
 
The leader would have powers to heal, to raise defenses and accuracy, things like that, like a buffer, and the controller would have poison, burning potions and some plant based attacks.
 
Leader example:
 
Ointment of Healing - Herbalist Recipe 1
A green liquid shines in the bottle. You or an ally drink it, as you shine and feel restored.
At Will * Primal, Healing.
Especial: This power can be used two times per encounter on the same target.
Standard
Target: You or an ally
Effect: The target can use a healing surge and regain an additional amount of HP equal to your WIS modifier.
 
 
Controller example:
 
Intoxication dust - Herbalist Recipe 1
You are rounded by a cloud of dust that damages to enemies who inhale it.
At will * Primal, Poison.
Standard - Burst 1
Target: Creatures in the burst.
Attack: Wisdom vs. Fortitude
Hit: Target takes an amount of poison damage equal to your WIS modifier.
Effect: Target takes 1 + lvl/2 poison ongoing damage (save ends)
 
It's only a base, I was wondering if these powers are overpowered or underpowered as herbalist is the first class I make. I would apreciate your help to balance them and your advices.
 
I'll look the artificer too to search inspiration.
 
Thanks for your help guys
