When to choose Rusty Tsuba

Take Rusty Tsuba for a Blade setup that blocks attacks with Sheath or Unsheath. Its evolution rewards 30 actual blocks, so the item fits a defensive rhythm you already use. Arges replaces Sheath; check which named action your setup retains before choosing this route.

  1. 1.Block 30 incoming enemy attacks with Sheath or Unsheath. Using either action in empty space does not meet the blocking requirement.
  2. 2.After it becomes Master’s Tsuba, its Weapon Damage bonus is +5/10/15.
  3. 3.For a 1.0.33 setup, read the invincibility-duration bonus as +40/70/120%. The +0.05/0.15/0.25-second values belong to 1.0.31 and should not be added to the later percentage bonus.

Recorded effect evidence

In 1.0.31, Rusty Tsuba grants Weapon Damage +2/4/6 and evolves after Sheath or Unsheath blocks 30 enemy attacks. Master's Tsuba grants Weapon Damage +5/10/15. Its Sheath and Unsheath invincibility bonus was +0.05/0.15/0.25 seconds in 1.0.31; 1.0.33 replaced those flat additions with +40/70/120% duration.

This is a historical record from version 1.0.31. The source has been reviewed; current tooltip values and live-game behavior still require in-game testing.

Official patch record

TEAM HORAY · 1.0.31 Update · 2026-09-10

The 1.0.31 announcement supplies the 30-block evolution requirement. The 1.0.33 announcement keeps Master's Tsuba Weapon Damage at +5/10/15 and replaces its flat invincibility-time additions with percentage bonuses; the two duration formats belong to different versions.

This is a historical change recorded in the linked official update, not a claim that every value still matches the live tooltip.
