I've got blades stashed in places you can't even IMAGINE!

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

A throwing kunai that deals damage and increases your movement speed each time it hits, a “ninja” type grenade. Made by Jakobs, the Legendary, it’s rare for a thrown weapon to crit, and the more you hit, the more “Ninja Speed” stacks up to a maximum of +70% movement speed. It’s a single throw that earns both offense and mobility.

🧩 Red Text Origin “I’ve got blades stashed in places you can’t even IMAGINE!” is considered a paraphrase/quote of Jack Sparrow from the movie ‘Pirates of the Caribbean: The Curse of the Black Pearl’ used to threaten his captors (MentalMars / multiple compilations). The name “Kunai” (kunai = ninja blade) matches the flavor of “hiding blades”. Because it originates from secondary compilation sources, the original source is (unverified) (will be added if primary source can be confirmed).
