Bonus Codex
The Sigil Forge
Compose your own Enochian sigil by tracing a path through the Watchtower of Air — name it, save it, share it. This bonus codex is unlocked when you and a fellow seeker both take the Vow.
How to unlock
Share your referral code from /upgrade. When a friend uses it to take any Vow, both of you instantly receive the Sigil Forge — forever.
