When a creature within 60 feet of you deals damage to you with a spell, you may spend a spell slot as a reaction to infect them with the crimson wasting. The Constitution saving throw DC to resist this disease is equal to 10 + the level of the expended spell slot. A creature that succeeds a saving throw against the crimson wasting is immune to further infections for 24 hours.

Additionally, you may inscribe up to seven necromantic spells of 1st level or higher into the libram of the crimson wasting. Your spell attack rolls, spell damage rolls, and saving throw DCs for these spells receive a +2 bonus.

A wizard may copy a spell out of the book if it is normally on his or her spell list; other characters may only copy rituals that they are able to cast.

History

This book, penned in the blood of three elder vampires, contains high and dire secrets of necromancy. It possesses a nascent will of its own, the confused and thirsting dreams of the three. It was written by a corrupted priestess, who used the libram of the crimson wasting to slay an angel and animate it as a vampire. To this day, the vampiric angel haunts the ruins near where it was created, spreading horror and a terrible thirst for blood wherever it goes.
