Yanmei's Knife Slash

Yanmei's Knife is a craftable Hardmode classless weapon. When swung, a short-ranged green slash appears in front of the player towards the mouse cursor. After the swing, the player is temporarily unable to use the item for three seconds. Striking a boss or its servants causes the user to gain the Kami Injection buff while the target is inflicted with the Kami Flu debuff. Kami Injection grants the player 15% movement speed and damage, while Kami Flu reduces the enemy’s damage reduction by 20% and depletes 125 health per second. Players with the Kami Injection will trail green afterimages, while targets that are inflicted with the Kami Flu debuff will emit a green glow.

The Yanmei's Knife cannot be reforged, and therefore cannot have modifiers.

Notes[]

  • The knife's effects only trigger on bosses, mini-bosses, and/or boss servants, making it hard to properly test against dummies.
  • When the knife successfully hits a vulnerable NPC, it will play the same sound as activating Adrenaline Mode.
  • The lowered damage reduction effect of Kami Flu does not work on The Dragonfolly, Polterghast, and Providence, the Profaned Goddess.

Tips[]

  • Due to the weapon's low direct damage and the significant stats of the buff and debuff, Yanmei's Knife should not be used as a primary damage-dealer and instead functions better when used periodically, to refresh the buff and debuff.

Trivia[]

  • The weapon is a reference to Automaid, a work-in-progress comic series being illustrated and written by the dedicatee. The knife is the signature weapon of the main character, Yanmei, with the Kami buff and debuffs playing a key role in the comic.
  • The tooltip is part of a poem by Piky, one of the beta testers for the mod, written to describe Yanmei:

A voice, a strike of caring humor
Sparking dear memories
Of sweetened & pure serenity
Memories of the Days of Old
Yet, profoundly reassuring
Her voice calls to the fire
Dancing until the break of dawn
Of her deeds alone, instilling within her friends
A heart of Valor
