Eternal IV MM2

Eternal IV is the purple Eternal and, despite its numeral, the fifth one released, because Eternalcane came out first. The wiki notes it is the last weapon modelled on a Roblox gear, here the limited Sword of the Eternal Abyss that every Eternal uses. The YouTuber JD leaked it a day before release, and it was heavily duped. Released on 20 May 2020 as a promo code shipped with shopmm2.com merch. That merch is sold out, so Eternal IV is trade-only.
