Equilibrium

You weave the fabric of reality around you, slightly shifting the scales of fate for up to [roll]2d4[/roll] friendly creatures within a 30 ft. radius of yourself. Each creature in range receives advantage on all attack rolls, saving throws, or skill checks (player's choice) while the effect lasts. However, while under the effects, they also receive disadvantage on one of the other two options. 

The effect for each creature lasts for the duration, or until that creature leaves the range of the spell.
