Special effect

Attacks no longer consume Sharpness, but 2% drains every second.

  • Class: Large Sword.
  • Class mechanic: Large Swords swing two wide slashes and an overhead slam. Every hit spends Sharpness; the Special — three rapid stabs — builds it back, and damage scales with the current Sharpness level.
  • Added: Early Access.

How to get

Hidden treasure in the Kalina Day Realm (blacksmith node).

Upgrading a weapon raises the number in its effect text. Each tier costs gold plus a growing count of the weapon's material, and the Legendary tier exists even though its full cost is not published.

Best use

Turns the Sharpness class into a time-limited burst weapon: swing freely, but end fights quickly before the passive drain empties the meter.
