Nuvolycan

Darkvision – Can see in dim light within 60 ft. as if it were bright light, and in darkness as if it were dim light. Can’t discern color in darkness, only shades of gray. Changing – Nuvolycans can change in and out of their alter form, but it takes a significant toll. The first time they change, it reduces their hit points by 1d4 (5) each time, cumulatively. For example, the first time they shift, they lose 1d4 (5). The second 2d4 (11), the third time they lose 3d4 (19), etc. Because of this, Nuvolycans must be very careful as morphing can dramatically (and perhaps fatally) drain their strength. Only available after L3. After a short rest, 1d8(6) is restored. After a long rest, all HP are restored.
