Any humanoid creature cursed with wererat lycanthropy retains its statistics except as follows:

• The creature gains the wererat’s speed in rat form, as well as the wererat’s damage immunities, traits, and actions that don’t involve equipment. It can’t speak while in rat form.
• The creature gains a Dexterity of 15 if its score isn’t already higher.
• The creature is proficient with the wererat’s bite attack. Attack and damage rolls for its bite are based on the creature’s Strength or Dexterity, whichever is higher. The save DC for the creature’s bite is 8 + the creature’s proficiency bonus + the creature’s Constitution modifier.
