Holding a bladed weapon, you point a finger at a friendly target other than yourself in range. For the duration of the spell, your magic grants the following benefit to the target: the first action, bonus action, reaction, or saving throw the target performs in a given round (whether their turn or not) is performed with advantage. 

One additional target may be chosen at 6th (two total and requires another finger to point at another target), one additional may be chosen at 12th (three total and requires three fingers used to point), and one additional may be chosen at 18th (four total and requires using a total of four fingers to point).

You must still hold the bladed weapon in one hand while concentrating on the spell. Losing the blade in some manner results in the spell being lost.
