Daar's party favors

Some favorites of Daar's action during a concert evening have been gathered into this spell. While touching an object specified in the effect, you create one of the following magical effects:

• You instantaneously tune an instrument you touch to the desired tone.
• You instantaneously make up to a quart of drink non-alcoholic in its touched container.
• An instrument that you touch has its volume raised or lowered for the duration. You may lower its volume down to one quarter or raise it up to four times its normal level. You can change the volume of one or more instruments affected by the spell as a bonus action while the effect lasts. The change is as gradual as you want.
• You create a mote of faintly glowing fuzzy energy, that fits in your hand. You may give this warmfuzzy to someone else as an action. When they accept the warmfuzzy, it dissolves around them, making them feel warm and cared for. A creature who is affected by a warmfuzzy and makes a saving throw to not be frightened has advantage on that roll, ending this effect. The warmfuzzy or its effect dissipates at the end of this spell.
• While holding a piece of paper, you create an invisible solid surface as a support under it as well as a spectral pen. You can write with the pen until the end of the spell - the ink becomes permanent. The invisible surface extends a bit around the paper to allow for forearm support.
• While holding an instrument, you can give one creature proficiency with this instrument for the spell's duration.
