Until the spell ends, you deal an extra 1d6 Force damage to the target whenever you hit it with an attack roll. You also have an Advantage on any Wisdom (Perception or Survival) check you make to find it. 

Level 3                 Hunters Sense, At 3rd level, you gain the ability to peer at a creature and magically discern how best to hurt it. Once Hunter's Mark is cast you immediately learn whether the creature has any damage immunities, resistances, or vulnerabilities and what they are. If the creature is hidden from divination magic, you sense that it has no damage immunities, resistances, or vulnerabilities. Cantrip doesn't require concentration, or a verbal component but needs a material component (Ranger/Druidic Focus).

Level 5                 Improved Hunter Mark, Extended range 120ft, duration 1 hour/level, can track target 1 mile/ level, from 5th level spell doesn't require concentration, or a verbal component but needs a material component (Ranger/ Druidic Focus).The Caster knows where the Target is despite being hidden or obstructed. 

Level 7                 Slayer, The damage die of your Hunter's Mark is a 2d4 rather than a d6.

Level 9                 Hunter Prey, The caster knows where the target is. If the character has a condition placed on them where disadvantage is considered, the Hunter's Mark remains in effect, and disadvantage is ignored. i.e. Target casts invisibility on themselves, or if the target becomes prone, but not if the target is prone when Hunter's Marks are placed on the target. Blinded, Frightened, Heavily Obscured, Hide, Invisible, Prone etc (use DM consideration i.e running behind a stone wall dependent on attack).
