Timepiercer

Alter: This item appears to be a sword hilt that has a small hole on either end of it. The hilt is made of clear quartz and contains an hourglass with sand inside it. Despite the holes on the hilt, the sand never seems to flow out of the hour glass. You can speak the hilt's command word as a bonus action to cause it to form a thin blade of sand. The hourglass spills sand from the bottom of the hilt that circulates up and around to form the blade and guard of the rapier before returning to the hourglass again through the hole in the top. You can speak the hilt's command word again as a bonus to cause all the sand to return to the hourglass. While the blade is formed, you gain a +2 bonus to attack and damage rolls made with this weapon.

While holding the hilt, you can use an action to cast either the haste or slow spell (save DC 16) from it. You can have advantage on concentration checks on maintaining these spells when cast in this way. Once a spell has been cast using the hilt, it can't be used to cast that spell again until the next dawn. The sands in the hourglass move quickly while concentrating on haste cast from the hilt, or more slowly when you concentrate on a slow spell.
