Bottle of Eversmoking

From TheReincarnation

This small bottle has a wooden stopper inscribed with magical runes. Once the stopper is removed, smoke billows out from the bottle and covers the whole sky for a given period of time, making the battlefield dark and shadowy. This gives the orcs a comfortable environment to fight in, since orcs have a hard time seeing in broad day light. This enhances their accuracy, thus boosting the power of your attack. Area of effects: all orcs, all enemy orcs
