  • To activate the "special attack", the wielder must combine its attack in the right order which is LMB>RMB>LMB>LMB>RMB click.
    • The maximum range of the special mode can reach is 5 meters
  • Since this weapon doesn't have or has very little knockback power, be careful while using it.
  • The blue sword (A mode) does 2 stab which have great stun power and deals very high damage on the second stab. The yellow sword (B mode) does 4 slashes in a quick succession but has low stun power, the last slash deals the higher damage.
  • This weapon is overpowered in a match of Knife Battle Team Deathmatch or Original, can easily kill opponents without much effort, especially when using the special attack.
Zombie Hero
  • The special mode last for 10 seconds, a great opportunity to kill zombies while it's active. Combine it with Deadly Shot for a devastating output.
  • Never face a Heavy zombie alone while using the swords, considering it has a really decent stun reduction as his passive skill.
  • Use A mode when facing a horde of zombies, as it has high stun power, long attack range and can hit multiple zombies at once.
  • There is a slight delay after using both modes.
    • Even in special mode, there are delays too. It is when activating the Sword Feast and after the Sword Feast ends.
    • To eliminate these delays, emote cancelling (J+3, hold left or right click) can be used, or quickswitching (Q twice). Whichever is faster depends on the user.
Zombie Scenario
  • Use its special mode to clear out hordes of zombies.
  • This weapon is a great barrier-breaker. It deals great amount of damage using any of its three modes.
  • There is a bug where the user can spam its attacks rapidly, by holding the respective mouse button and pressing F2 rapidly in buyzones. This bug also happens with Warhammer Storm Giant.
  • This weapon has the greatest DPS against bosses out of any currently-released weapon. The second stab of A mode is capable of reaching upwards of 600,000 damage, with a critical hit to a boss's weak point. Oberon's Horns are recommended. Using the above F2 trick, its DPS nearly doubles.
