The Tree and Cockroach? (edited)

Why exactly was it around that percentile?

Was the item so powerful it could nearly kill anything with that much accuracy?

Was it the reason why the assassin family, Roselle, had been such an intimidating force in the underworld?

Or was it because of the Heroine's incapability to survive it in the early stages of the game?

The latter would be the most accurate.

In the entirety of the game, Marionette was seen only using this congratulatory javelin in the early stages. And only so when you have either antagonised or disturbed her enough that forces her to waste it on you.

For what deep reason did the creators have in mind for this? No one knew.

But what everyone knew was that in the early stages, the heroine was far incapable of dodging such a blitzing throw.

Lillian stared at the javelin that soared through the air.

Like a shooting star of trailing stardust, the javelin flew with silent crimson bloodlust.
