A "thrust attack" is a melee strike that intends to hit an enemy with the tip of the blade (the rounded edge of obround melee hitbox). A "360/spin attack" is a sliding sweep attack that hits targets around the player (not always in a 360° arc, but is usually above 180°). A "direct slam attack" is a melee strike that hits a single target at the epicenter of a slam attack. Affected by the Seismic Wave mod. A "radial slam attack" is the area-of-effect component of the melee slam attack. Affected by the Seismic Wave mod. A "ranged attack" is any melee attack that launches a ranged projectile or can hit targets beyond melee range. View Full Legend Average Damage Multiplier per second only applies to single-target DPS calculations. Note that hits marked as "Radial Slam Attack" will not apply at the epicenter of a single target hit so these will not be accounted for in Avg Dmg Multi/s calculations. Combo animation lengths are approximate and are only accurate within a few tenths of a second. Each tile marking in stance preview gifs are 2m apart. Combos labeled with an asterisk (*) are shared between weapons within the same weapon type.

Notes

• Warfan slams hit twice.
  • Second hit of a heavy slam will use the stats of a normal slam.

Trivia

• The name of the weapon may have come from the English word "Arum", and Italian word "Spinoso".
  • The arum is a flowering plant seen in Europe, northern Africa, and western and central Asia.
  • "Spinoso", in Italian, means "Prickly", or "Thorny".
