Despite the passive belonging to Sheath Knight, the passive icon displays Infinity Sword's weapon.
This passive acts as a replacement for the previous passive, Fighting Spirit, which had the same effect of making all hits critical for a certain period, though it was tied to Brutal Slayer's MP burn effect at the time (which still shares the same activation rate as this passive does).
