Alchemy was a bit of a throwaway skill in the past games. Potions were supportive, but not essential. You may start out making interesting potions when your skills are low, but when you level up, you find yourself only using healing potions. There should be a higher tier of potions which provide immense benefits to the player if they are made properly.
The ingredients for these potions would be hard to come by or very expensive. Perhaps there is a monster which is rarely seen and extremely difficult to kill, they would have a high tier ingredient.
Alchemy just needs to be given a greater importance in the game.
