Ashes of darkness

Usually carried by famous rogues, these small bottles are called "Ashes or Darkness". The liquid inside the bottle is imbued with potent magic, and when the cork is removed, the essence of a dark elemental is released in a sudden burst of smoke and darkness. The effect is almost instantaneous, creating a thick cloud of dark smoke that spreads out, obscuring the vision of anyone caught in its wake.

This magic item is highly prized by thieves and spies, as it allows them to create an instant smoke screen and disappear from sight. The darkness and confusion created by the smoke provide an excellent cover for escaping unnoticed or launching a surprise attack.

Zone of darkness (Object action): As an object action a character that uses a bottle of ashes can cover a 30 ft cube. The zone will turn into a slighty obscure area in the first turn, in the second turn it will be considered a heavily obscured area and will also produce a muffle effect inside said area. The darkness is magical and cannot be dispelled without a daylight spell.
