Vecna’s benediction

Following vision during the ritual, advantage to Insight checks, and once per long rest, possibility to cast See Invisibility.

The Vision :

Around the world and across the planes, you perceive innumerable cults of Vecna. They snatch away people and strip their secrets in rituals like the one you stopped. Behind them, the withered form of Vecna gathers the secrets like threads, adding them to a glowing sphere of hidden knowledge in some impossibly distant place. The vision fades into darkness, leaving only Vecna’s glaring left eye.
