The Worgen are wolf-like humanoids that are a result of the worgen’s curse, a remnant of the Druid’s forbidden Pack Form being altered by the Scythe of Elune. The worgen’s curse can also be spread through claw attacks or consuming the blood of a worgen.
Instead of being a strict race, you instead take this as "extra" racial features, or from the result of the Worgen curse. If you become a worgen, regardless of the method, you gain the following:
Two Forms : As a bonus action, you can change between your native form and worgen form. While in worgen form, you gain the following:
You gain darkvision of 60 feet. If your race already has darkvision, it is increased by 30 feet.
You gain a natural claw attack. This claw attack is treated as having Light and Finesse, and deals slashing damage equal to 1d4 + your Strength or Dexterity modifier.
Gain Darkflight.
Darkflight : While in worgen form, when you move on your turn in combat, you can double your speed until the end of the turn. Once you use this trait, you can't use it again until you move 0 feet on one of your turns.
