Alasar's Alacrity

Like a sudden surge of adrenaline, arcane energies flow through the target, enhancing all of the targets physical abilities, sharpening the mind, and even fortifying their resolve. 

You enchant up to three creatures of your choice within range. Whenever a target makes an attack roll, saving throw, or skill check before the spell ends, the target adds +2 to the roll.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each slot above 2nd.
