In Baldur's Gate: Descent Into Avernus, on pages 226-227, the
Sword of Zariel
is described. The weapon is listed as a
Weapon (longsword), artifact (requires attunement by a creature the sword deems worthy)
and has the following property (given a bold italics header):
Attunement. The sword allows you to attune to it immediately, without having to take a short rest. The first time you attune to the sword, you are transformed into a heavenly, idealized version of yourself, blessed with otherworldly beauty and a touch of heaven in your heart. Neither magic nor divine intervention can reverse this transformation. Your alignment becomes lawful good, and you gain the following traits:
Briefly, these traits include (give bold headers):
Angelic Language (you can speak Celestial), Celestial Resistance (you have resistance to necrotic and radiant damage), Divine Presence (your Charisma score becomes 20), Feathered Wings (gives you flying speed of 90 feet), Truesight (for 60 feet) and a New Personality (you pick new traits from tables included in the book).
The next header is written in bold italics, so I believe this is a new property that is unrelated to the Attunement property.
My question is about the part that says:
The first time you attune to the sword, you are transformed into a heavenly, idealized version of yourself [...] Neither magic nor divine intervention can reverse this transformation.
As I understand it, this means that you are permanently given all of the various traits, regardless of whether you remain attuned to the weapon or not, or whether or not
Zariel gets the weapon back and keeps it (after being redeemed, pp. 146-148) or even destroys the weapon (p. 152).
Is this interpretation correct? Does that even mean that an entire party could pass the weapon around (assuming that
the weapon "deems them all worthy")
and all gain these traits forever afterwards, even if
Zariel destroys the sword (then presumably having to deal with a party of flying super-charismatic semi-angelic PCs)?
In short, this seems really overpowered (in that you can be permanently changed and you don't even need to keep the weapon afterwards); am I reading this right?
