Engineers Mark

You choose a creature you can see within range and quickly mark it as your quarry. Until the spell ends, you deal an extra 1d6 damage to the target whenever you or an ally hits with a weapon attack, and you have advantage on any Wisdom (Perception) or Wisdom (Survival) check you make to find it. If the target drops to 0 hit points a DC 15 tool skill can be made to retrieve the marker as an action but may remark another creature as a bonus action until the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 3rd, 5th, 7th level, DC for crafting decreases by 5 points every two levels casted above.
