Arum Spinosa GUIDE

Understand Arum Spinosa

Useful when…

  • Use normal attacks for its listed Slash-heavy damage and 37% status chance.
  • Use the heavy-attack projectile mode for its separately listed damage and status entries.
  • Distinguish its projectile heavy attacks from its area slam modes.

Normal attacks

Normal attacks list 297 damage: 201.96 Slash, 59.4 Puncture, and 35.64 Impact. They have 9% critical chance, a 1.9× critical multiplier, and 37% status chance, at about 1.08 attacks per second.

Toxic-spine heavy attacks

The first toxic-spine projectile entry lists 175 total damage, including 72.5 Toxin, and 6.16% status chance. The second entry lists 350 total damage, including 145 Toxin, and 12.3% status chance. Both entries list a 0.5-second charge time and projectile speed and flight of 49.

Slam attacks and handling

Regular slams list 594 Impact damage, 10% status chance, and falloff out to 5 m. Heavy slams separately list 891 Blast damage, 28% status chance, and falloff out to 6 m. The weapon also lists 1.7 m range, 0.7 follow-through, a 0.5-second heavy-attack wind-up, and a five-second combo duration.

Limitations and tradeoffs

  • The normal critical chance is 9%.
  • The two toxic-spine projectile entries have different damage and status values.
  • The listed normal range is 1.7 m; the projectile attacks are a separate mode.

Common mistakes to avoid

  • Do not give both toxic-spine projectile entries the same damage or status chance.
  • Do not describe the ranged heavy attack as a normal melee strike.
  • Do not conflate the heavy-slam Blast attack with the toxic-spine projectile.
