Vortexic bolt

A green Vortexic bolt flies from the caster's gem towards a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 6d4 Force damage, and the next attack roll made against this target before the end of your next turn has a  + spellcaster spell casting ability modifier, thanks to the mystical energy that was focused from the caster through the gem on the target until then.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
