VULCANUS-9 Confirmed Set[]

VULCANUS-9 Confirmed Set

A set that includes VULCANUS-9 Perfect Pick Recipe, the specified blueprint with S grade, permanent durability and 16000 points.


  • There are 3 forms for this weapon; normal form which has moderate rate of slash and low damage (can attack a single target only), Vulcanus form which has lower rate of slash with burning effect that deals very high damage and applies an afterburn effect, and without the burning effect which deals lower damage (but still higher than normal form) and applies no afterburn effect when the ammo is drained. (Vulcanus form in both states can attack multiple targets in an area of 180 degrees)
  • There's no condition to activate the Vulcanus form, but the extra damage from the burning effect requires ammunition to be at least 1 gas box. However, the ammo can regenerate itself automatically when switching to the normal form.
    • When in normal form, it will generate ammo again instantly. In case the player keeps fighting in Vulcanus form with no ammo, it will not generate any gas box.
  • VULCANUS-9 can generate up to 10 gas boxes as maximum. Upon using B mode, it will flame up and deal high damage. If the sword runs out of ammo, it will stay as is - The user will remain wielding it in the Vulcanus form but without taking advantage of the extra damage from the burning effect.
  • It takes 2 seconds to transform to Vulcanus form as well as in contrast.
    • Beware that attacking right after activating B mode way too quickly will not apply the burning effect, therefore dealing lower damage and no afterburn effect. However, attacking in this form deals higher damage than in the normal form.
  • When regenerating, it takes 1.5 seconds between each gas box. Totally, it takes 14 seconds for a full recharge. However, the player does not need to wait until full charge to take advantage of the extra damage in Vulcanus form.
    • VULCANUS-9 ammo can be quickly refilled when you re-buy it in a buy zone, or buying another melee weapon and rebuying VULCANUS-9. This is a good trick to quickly its ammo. Please note that you must be in normal form or have switched to another weapon to be able to re-buy VULCANUS-9 directly.
  • VULCANUS-9 can inflict an afterburn effect against multiple enemies in Vulcanus form.
    • It can also be inflicted on your teammates if friendly fire is allowed.
  • The indicator on the blade's cross-guard notifies the user of the gas combustion level, going from reddish at the highest to yellowish as it depletes.
  • VULCANUS-9 can perform 1-hit-kill in Original modes, even with armor (except for legs) in Vulcanus form with the burning effect. If the burning effect vanishes, it requires 2 slashes to kill a player.
