Ripper

 You’ve learned to fight like an animal, granting you the following benefits:

• Increase your Strength or Dexterity by 1, to a maximum of 20.
• Once per turn when you hit a creature with a natural weapon attack that deals damage, you can reduce the speed of the target by 10 feet until the start of your next turn.
• When you score a critical hit with a natural weapon attack that deals damage to a creature, you can roll one additional damage die when determining the extra damage the target takes.
