Alchemical Potency

You gain proficiency with alchemist's supplies.

When you make a concoction using your alchemist's supplies you gain a few bennifits:

--The number of concoctions you can create is increased to equal Double your Proficiency Bonus, so long as you have enough raw materials.

--It now only costs 10gp of raw materials to create a Vial of Acid or Alchemist's Fire. Additionaly, you can use 25gp worth of raw materials to create a Potion of Healing.

--Your Concoctions act as improvised weapons with which you are proficient. When you attack with them you can add your Intelligence modifier instead of Strength or Dexterity plus your Proficancy Bonus. Your concoctions have the Light, Finesse and Thrown(30/60) properties. 

--The number of dice you now roll for your concoctions equals your proficancy bonus.
