So I'm planning on house ruling that alchemists can get Infusion discovery for free. It's more fun when characters don't die (easily), and having healing from an alchemist would help. Plus, it doesn't make a ton of sense having self only potions. Also, as far as I see it the Cleric class gets a lot of nice abilities to balance having to spend a lot of their time healing others. Why should an alchemist have to pay for the same privilege?
Anyone have a good reason why I shouldn't house rule that?
Well there's almost twice as many discoveries now. You can get Infusion at level 2 if you want. Also the Alchemist now get's Brew Potion at level 1 for free, which let's you brew a potion of any spell you know 3rd level or lower.
