Description

Acidum Rifle is a gun sword in Blox Fruits and slots into the broader sword tier list around the gun-rank baseline. Whether it's worth chasing depends on your build: pure-fruit mains usually skip mid-rarity swords entirely, while sword-mains and combo PvPers chain weapons to alternate movesets without the cooldown overlap that comes from spamming a single fruit. Common swords are starter-tier weapons. Use them to grind early mastery levels and immediately upgrade once you can afford an Uncommon or higher. Pair Acidum Rifle with a fighting style that complements its swing speed — Godhuman or Sanguine Art covers any sword's M1 gap with bursty kicks, while Death Step's range trade is the classic combo extender. As a sword, Acidum Rifle draws from your sword stat pool, so respeccing into 2,500+ sword stat is a hard prerequisite to hit its full damage ceiling. Mastery scales with hits landed; M1 spam during low-level grinding is the fastest way to climb early, then transition to skill-spam against bosses for the multiplier. It costs free / quest reward from the relevant NPC vendor, premium shop, or quest reward — keep an eye out for the related sword dealer or boss drop chain when you reach the corresponding sea. If your loadout already has a higher-tier sword, Acidum Rifle can still earn a slot as a swap option — Blox Fruits' "Z + sword swap" tech is one of the fastest ways to chain skills without giving the enemy a recovery window.
