I still would love a Scholar class with Plague Doctor and Apothecary subclasses. They could upgrade basic purchased items.
				
			- Updgrding healing potions with more healing or special benefits
 - Acid becomes Corrosive Bombs
 - Antitoxin distilled Purification Vials
 - Alchemist's Fire focused Fire Bombs
 - Basic Poison concentrated into Poison Grenades and Plague Grenades
 - Holy Water can be distilled into Antideath Grenades that heal living and harm undead
 - Return of tanglefoot bags and thunderstones with the addition of choking and blinding powders
 - Special drugs that make you go fast, keep you awake, see in bullet time, ignore pain and more
