Your soul have touched by vampires. You still look normal but when you look into a mirror you see a horrifying monster or your vampire soul.

Starting at 3rd level, you gain proficiency with firearms (You may use the rules for firearms of the Dungeons Master's Guide or the Gunslinger rules). You also have proficiency with Tinker’s Tools. You may use them to craft ammunition at half the cost, repair damaged firearms, or even draft and create new ones (DM’s discretion).

Vampire soul Spells

At 3rd level, you learn an additional spell when you reach certain levels in this class. Each spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you know. You can use a Tinker's Tool as a arcane focus.

Soul of a Vampire

At 3rd level your vampire soul can appear. If you are in dim light or darkness you transform into your vampire form. The moment there is bright light you transform into your normal form again and loose all the abilities granted by your vampire form. In your vampire form you gain these benefits:

Vampire Feeling. You are considered undead when in your vampire form.

Spider Climb. You can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Bite. As an action you can bite a creature. You use your Dexterity + your proficiency bonus to hit and it does (1d6 + Dexterity) piercing damage. You also gain half the damage (rounded down) as temporary hit points until you take a short or long rest (you still keep the temporary hit points if you revert to your normal form). The damage die for your bite increases to (2d6) at 5th level, (3d6) at 7th level, (4d6) at 11th level and (5d6) at 15th level. At 11th level your bite becomes magical to overcome resistances and immunities.

At 7th level, you can, as an action,  you can polymorph into a Tiny bat or into your vampire form.

As a bat you use the stat block but you keep your Hit Points and Armor Class. You cannot speak and gain the traits of the Soul of a Vampire feature. If you die in this form you revert to your normal form.

In your vampire form you gain the features from Soul of a Vampire, and you gain a trait: If you standing in sun light you take 1d6 radiant damage and if your standing in running water you take 1d6 acid damage. You can only stay in your vampire form for 1 minute. If you die in the form you turn to dust.

 

Soul Strike

At 11th level when you hit a creature, your vampire soul can attack a creature up to 20 feet away (can be the same creature or different). The vampire use your Wisdom modifier and it does 1d10 necrotic damage. You can only use this feature equal to double your proficiency and regain uses every long rest. The damage increases at 11th level (2d10), 15th (3d10) and at 18th (4d10). 

Vampire Mastery

At 15th level, if you take damage form a creature within 30 feet, as your reaction you can do an attack on them using your bite from the Soul of a Vampire feature.
