Shifter Wildhunt Elite

Your enhanced senses make you an elite tracker and your shifter trait improves: You can Mark The Scent.

• As a bonus action, you can mark a creatures scent within 10'. Until the end of your next long rest, your proficiency bonus is doubled for any ability checks you make to find the marked creature, and you always know the location of that creature if it is within 30 feet of you. (You can only have one marked creature at a time).
• You can not have disadvantage on attack rolls against a marked creature if it is within 30 feet of you. 
• You can use wisdom in place of intelligence for investigation checks about the creature.
• You can remove the mark or move it another creature as a bonus action.
