The Squall Knife is a Demon Unique dagger with no boss attached: it drops in Adventure Mode once you are level 21 or higher, and keeps dropping there however far you go. Every copy is item level 26, and there 0.8% of what falls comes up Unique. It is built on Worn Throwing Dagger — step 2 of the Throwing Dagger line, item level 15 and up.

It always rolls the same numbers: +14 Power, +8% Attack Speed, +9% Projectile Damage, +15% Projectile Speed, +16% Projectile Damage, +23% Projectile Speed and +10% Attack Speed.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries The Squall Knife — Your Main throws 2 more knives in a 25% wider spread, at -15% damage.

Wearing it hands you Knife Toss.

“Throw enough and one drop is always yours.”
