Potion of gain energy

Potions of gain energy are largely useful for spellcasters and alchemy; depending on whether it's blessed or uncursed, it will give you from 2 to 11 spell points, increasing your maximum by the same, and exercise your wisdom. Cursed potions will decrease your points, but still exercise your wisdom. For alchemy, mixing gain energy and healing/extra healing will produce an uncursed and diluted potion of extra or full healing. If you dip a potion of confusion into gain energy, you will get a potion of enlightenment or booze, with booze occurring two times out of three.
