Trexial's Dazzling Fire Bolt

You hurl a mote of sparkling fire at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 fire damage and is covered in sparkling light until hit with another attack or the beginning of your next turn, whichever comes first. All attacks against target have advantage until sparkles fade. A flammable object hit by this spell ignites if it isn't being worn or carried. 

When cast at 3rd level or above, this spell's damage increases by 1d10 for every second level above 1st.
