Fire Potion

With the introduction of lush caves and spore blossoms, there should be a way to extract oil from the open blossom or from the hanging azalea roots and put the oil in a crafting table with fire charge, blaze powder, or flint to make a potion/Molotov that lights players and mobs on fire. There could be drinkable, throwable, and lingering potions of fire. Another option could be in a brewing stand. By putting the bottles full of "azalea oil" in the three bottle slots and putting a blaze powder or fire charge in the top slot, allowing the fire potion to be made. To make it even more challenging and less overpowered, the oil could be collected in goat horns.
