Permanent transformation

Prerequisite: Druid levels or the shifter race or a similar shapeshifting feature.

You have become so well adept at altering your physical form into a temporary beastial form that some of its aspects have become permanent. Your develop visual changes that resemble the form you most often transform into and you gain the following benefits.

• Beastial movement. The claws, fins or other animalistic elements of your new form grant you the ability to move in new ways; you gain your choice of either a climbing, swimming or burrowing speed  equal to your walking.
• Natural weapons. The ferocity of your form allows you to use your body as a weapon, using a natural weapon appropriate to your favoured form such as a sharp teeth or a claws. You are proficient with this attack, it has the finesse property and uses a 1d8 damage die. Additionally when you take the attack action on your turn you can make an additional attack using this weapon as a bonus action. If you are in another form (for example while using the wild shape feature) this bonus action attack still uses a d8 even if your new form would usually use another die when determining damage.
