HyperWeapon / Calamity Fusion
In the game data, a calamity weapon is a weapon whose technical subtype is Hyper. It has a Calamity Fusion progression from 0 to 5, Weapon Potentials, and one strict rule: the Potential only works if the character masters that weapon type.

Perpetual Strife
One who bore this weapon was a warrior, granted it by Father Ask in honour of his valour. He sought ever mightier foes, sending challenge after challenge to distant lands. His name became a byword for strength, until at last he could no longer live without battle. War granted him no release. He fell within it — an arena without victor or end. The bodies of friend and foe alike became his salvation, and his own blood his final elegy.
