Herald of Vecna

Herald of Vecna is a feat imbued with dark powers and a deep connection to the Lich Lord Vecna himself. Those who attain this feat have fully committed themselves to Vecna’s dark wisdom and malevolent power, becoming vessels of his unholy influence. This bond bestows upon the Herald profound and terrible abilities, enhancing their dark craft and granting them dominion over the whispers of the dead and the secrets of the unknown.

Vecna's Whisper. You can communicate telepathically with any creature within 60 feet that you can see, provided they understand a language. This communication allows you to subtly influence their thoughts, imposing disadvantage on any Wisdom saving throw they make within the next hour.

Necrotic Shield. Once per long rest, you can invoke Vecna's protection, creating a shimmering shield of necrotic energy around yourself. This shield grants you a +3 bonus to AC for 10 minutes or until you are struck by a radiant damage attack.

Soul Syphon. Once per day, you can perform a 10-minute ritual to drain life essence from a recently deceased creature. This essence restores hit points equal to 3d8 + your spellcasting modifier. The creature must have died within the last hour, and its soul is irrevocably consumed, preventing any resurrection magic from bringing it back.

Dark Dominion. Your connection to Vecna grants you the ability to command undead. As an action, you can force all undead within 30 feet to make a Wisdom saving throw (DC = 8 + your proficiency bonus + your Charisma modifier). On a failure, they are charmed by you for 1 minute or until they take radiant damage.
