Your intelligence score increases by 2 and your dexterity score increases by 1

You can use your bonus action to close your eyes and sharpen your senses of hearing and smell to locate people near you. When used, everyone in a 30ft radius must make a dexterity (stealth) saving throw (DC = 10 + your perception modifier) or have their location revealed to you. For each 10 ft the ability extends beyond 30 ft, the DC decreases by 1 to a maximum of 60 ft away.

Using your superb sense of smell, you can easily detect and follow scents. Whenever you roll survival to track something, you gain not only advantage but also double any modifiers that may apply to the roll. You are also able to tell what the scent is, how long ago it was, and can follow it through any terrain. This also allows you to detect and identify any smell you come in contact with when you roll to detect it.

Once per turn you can use your action to bite and hold your enemy in place. When you use bite, roll to attack. If the roll passes their armour class, you bite down onto your opponent, dealing 1d4 + STR modifier slashing damage. Furthermore, the enemy must roll a strength check or a dexterity (acrobatics) check contested by a strength check of your own. If your roll surpasses theirs, they are grappled using stardard grapple rules, except they are pinned down with your maw. If their check surpasses yours, they escape being grappled and are not effected.

Escaping the grapple.

To escape the grapple effect of bite, the grappled person must use their action to roll a strength check or a dexterity (acrobatics) check contested by a strength check of your own. If your roll succeeds, they remain grappled and take an extra 1 slashing damage for writhing around while bitten. If their check succeeds, their either slip out of the bite or pry your mouth off (depending on the roll type)
