 Uncursed potions of invisibility are useful for escaping or clearing out tricky combat situations early in the game, but will usually not be as reliable once a hero gets off the ground. A blessed potion is a quick and easy way to attain permanent invisibility, provided the hero also has a mummy wrapping or other means of handling shopping (or else is not concerned about it). A hero that is already permanently invisible or does not plan to become permanently invisible may consider non-cursed potions of invisibility a good candidate for [[dilution]].
