Therianthrope of Prey

You’ve given in to feral instincts that help you hunt down prey through your bestial form. 

You can assume your bestial form as a bonus action. While in this form you gain the following effects for 1 hour. Once you assume your bestial form you must finish a long rest before you can do so again. 

• When you hit a creature with a melee weapon attack you can mark that creature as prey. You have advantage on strength checks made to grapple the creature marked this way. Wisdom checks to track the creature marked this way are made with advantage for 8 hours. You can only mark one creature in this way at a time.
• You gain advantage on attack rolls against any creature you are grappling and you can grapple large or smaller creatures.
  
• Your unarmed strike uses a d4 for damage. At 6th level your unarmed strike uses a D6 for damage. At 12th level your unarmed strike uses a D8 for damage.
