Curse of Vampirism

You rise as a vampire, an immortal creature that feeds on the blood of living creatures and immediately gain the Vampire racial style class and its key ability. Your race changes to ‘Vampire’, but you keep the benefits of your previous race.

As a vampire, you no longer age and your physical appearance changes slightly. Your skin becomes more pale and you grow a pair of fangs. You still need to eat, drink and breathe as normal.

A vampire’s spirit core is cracked, making it difficult for it to regenerate mana naturally and requiring it to obtain it from other creatures. You no longer regenerate mana from eating (including potions), resting and can no longer use the Draw Mana encounter conclusion action. You still recover full mana at the start of a new arc. 

You are weak to sunlight. Every round you spend in sunlight without proper protection you take 10 true damage and your maximum HP is lowered by 10. Your maximum HP remains lowered until you finish a rest. You may carry a parasol or similar object in one hand to protect yourself from the sun and can do so even in combat.

In addition to these drawbacks, you no longer receive Wounds unless the damage that reduced your HP to 0 was fire, holy or true damage. You also gain 60ft Darkvision. Darkvision lets you see in total darkness, even if there's no source of light.
