Bolt of Planar Lightning

Your body glows with an aura of energy seeping into this realm from across doorways to the multiverse.  The energy masses at your feet and swirls up your body, enveloping you like a robe until it intensifies around your head.  A flash of interdimensional energy blasts from your eyes and streaks toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6+1 radiant damage and 1d6+1 lightning damage (modified by your primary skill), and the next attack roll made against this target before the end of your next turn has advantage, thanks to the glowing after effect of interdimensional energy.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
