Potion

Very Rare

When you drink this potion, you become cursed. While
cursed in this way, you gain darkvision out to 120 ft. if you did
not have it already, and whenever you receive necrotic
damage, you instead heal the amount of damage you would
have taken. In addition, whenever an undead creature with
less than 10 Intelligence targets you with a harmful attack or
spell, it must first make a DC 18 Wisdom saving throw. On a
failed save, the creature must choose a new target or lose the
attack or spell.


Every night at midnight while cursed, you must succeed on
a DC 18 Wisdom saving throw or become dominated by the
death knight from whose blood this potion was crafted, as if
under the effect of the dominate person spell, but with an
indefinite duration, no concentration required, and unlimited
range. The death knight is aware of this taking place unless it
is on a different plane of existence.


This curse can only be removed if the death knight from
whom the blood was taken is permanently destroyed, after
which point the curse immediately ends.
