Chaotic Sling

You launch a mote of twisting chaotic energy Make a ranged spell attack against a single target.  Roll 2d4 for damage.  The number rolled on that die determines the attacks damage type, with 1 being Acid, 2 being Cold, 3 being Fire, and 4 being Lightning. If the numbers rolled are the same, roll 2d4 for additional damage.  The chain can only happen once a target.  The spell creates more than one mote when you reach higher levels: two motes at 5th level, three motes at 11th level, and four motes at 17th level. You can direct the motes at the same target or at different ones. Make a separate attack roll for each mote.
