Arcane dart

A small dart surrounded by arcane energy flies through the air when you throw it propelled by your magic ability slamming into one creature of your choice within range.  The creature will take 1 piercing damage (the dart), and also take 1d10 damage of one of the following elements fire, lightning, ice, or poison.  If you wish to use concentration every turn when it comes to the opposing creatures turn it takes 1d6 damage of whatever element you chose in the first place.  If they succeed a constitution saving throw then the concentration ends and you will deal no more damage for that spell.
