Basic Rules (2014) - Modified
1-level Divination
You choose a creature you can see within range and mystically mark it as your quarry. Until the spell ends, you deal an extra 1d6 damage to the target whenever you hit it with a weapon attack, and you have advantage on any Wisdom (Perception or Survival) check you make to find it.
If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to mark a new creature.
Your concentration can last longer with a spell slot of level 3–4 (up to 8 hours) or 5+ (up to 24 hours).
