Weapon Description

“A giant scissor blade used by a Nameless puppet. It is a double-edged sword that can end one’s freedom, or grant it by cutting the strings of manipulation.

Puppets are tied to strings. Humans have cut their own strings. The boy made a choice and became human.”

The Proof of Humanity’s fast and aggressive moveset, damage output, and combination of Fable Art all make for a powerful special weapon that lets you burst down the enemy’s HP with ease. This boss weapon has a B scaling for both Motivity and Technique and is excellent for quality builds.

The Proof of Humanity has the Link Slash and Grind Fable Arts. The latter increases your critical hit chance for a short period which synergizes well with being able to throw out a flurry of strikes with good range. The weapon gives you access to dual-wield attacks such as a fast crossing sweep and a spinning slash, both of which are extremely effective for hitting multiple targets within range.
