Dazzling Trap

You set a small vile of colorful dust or ink into the ground and carefully place an invisible magic tripwire from the vile no longer that 30 ft. Once placed, any creature that crosses the tripwire sets off the trap creating a loud bang and causing the vile to explode with a colorful burst. The target takes 1d6 force damage and must make a dexterity saving throw with a dc equal to your spell save dc or become marked with the dust or ink. This gives you advantage on ranged attacks against the target for 1 minute. If nothing triggers the trap during the spells duration then you may harmlessly collect the vile. 

If you cast this at a higher level the damage is increased by 1d6 for each level above 2nd
