Item from Overlord by Kugane Maruyama
The guild weapon of Ainz Ooal Gown — crafted from divine-class materials by all 41 members, capable of casting powerful spells autonomously, and the single most valuable item in Nazarick.
The Staff of Ainz Ooal Gown is the guild weapon — crafted from divine-class materials contributed by all 41 members. It amplifies Ainz's already overwhelming magical power, can cast spells autonomously, and is stored in the Treasury under Aureole Omega's guard. Destroying it would deal devastating damage to Nazarick's defenses. Ainz almost never uses it publicly because he's terrified of losing it. His hoarding instinct overrides his strategic sense — a pure MMO player behavior that his subordinates interpret as 'saving his greatest weapon for the ultimate battle.' In reality, he just can't stand the thought of his friends' work being damaged.
An elaborate staff topped with seven serpents, each holding a gem in its mouth representing a different element. The staff radiates power visible even to non-magic users. It is both a weapon and a symbol of the guild's collective achievement.
