While Shifting, the size of the Longtooth Shifter’s canines increases. They can use these knife-like teeth in an
unarmed strike. This bite attack causes 1d6 + STR modifier piercing
damage. This unarmed attack is interesting because it is a bonus action. Because players attack with their teeth, a character can still wield a sword and shield and perform this attack. A Longtooth Shifter
Fighter could perform three attacks in one turn from an early level.
