Embrace of Darkness

For sixty minutes, you embrace a terrible blood-curse and become one with the beast within. Only a Dhampir of neutral alignment may cast this spell; Dhampir of evil or (much more rarely) of good alignment, cannot balance and reason the moral platitudes of the transformation and become hostile to any and everything, devolving into beasts that hunger only for blood, their alignment becomes, permanently, chaotic evil and they cannot be charmed.

A neutral Dhampir must pass a (DC17) Wisdom saving throw or similarly become hostile and chaotic evil to all those around them, though they can be charmed and suffer disadvantage on their rolls until the next long rest, by which time the magic will have passed from them and they will return to their normal state, with only vague memories of what they may have done.

This spell imbues the caster with not only great fortitude, but the strength and dexterity of an elder vampire, causing the caster to gain 7d10 temporary hit-points for the duration, +7 to Strength and Dexterity scores and expertise in hand-to-hand combat, for the duration. Their eyes glow a baleful, hungry red color - you recieve a +6 bonus on all perception rolls, as your senses are enhanced by the curse, but also suffer from Sunlight Sensativity for the duration. The caster's fangs grow long and jagged and they gain long, scythe-like claws; these count as +4 magical weapons and attacking with them has a one-in-four chance to drain 2d6 life from the target creature, unless it is Undead.

You also recieve the ability to cast Misty Step at will, without expending a spell slot, twice. You may also cast Eyebite once, as a bonus action. You are vulnerable to fire and radiant damage, as well as silvered weaponry, but become immune to Ice, Necrotic and Poison damage, for the duration.

After sixty minutes pass, you gain three levels of exhaustion and take 3d10 points of necrotic damage, as the temporary boost of vitality fades from you and the grim powers of undeath exact their toll. If you die by this effect, you rise at midnight as a full-blooded vampire, with all the detriments and benefits that may hold for you.
