Heat Sword

Slash-focused sword

Released Dec 18, 2012

Heat Sword is a Mastery Rank 3 sword whose normal attacks are heavily weighted toward Slash, while its slam modes deal Heat area damage. Consider it as an early sword if you want that split between direct Slash attacks and Heat slams.

Heat Sword GUIDE

Understand Heat Sword

Useful when…

  • Close-range sword combat emphasizing Slash damage.
  • Using the separate Heat slam attacks against nearby enemies.

Normal attack profile

The normal attack deals 147 listed damage: 117.6 Slash, 14.7 Puncture, and 14.7 Impact. It has a 5% critical chance, 1.5× critical multiplier, 20% status chance, and about 0.917 attack speed. Listed range is 2.5 m and the combo duration is 5 seconds. The normal attack does not list innate Heat damage despite the weapon’s name.

Slam modes

The regular slam is a separate area attack listing 294 Heat damage, 20% status chance, and 50% falloff by 7 m. The heavy slam lists 441 Heat damage, 20% status chance, and 30% falloff by 8 m. Keep these Heat slam values separate from the Slash-heavy normal attack.

Mod fit and alternatives

Heat Sword ranks to 30 and has one Naramon polarity for a matching-polarity mod. Cronus and Jaw Sword are also swords, while Dark Sword’s description specifically identifies innate Radiation damage. The supplied comparisons do not give enough detail to rank those swords against Heat Sword; consider Dark Sword if that named damage type is the feature you want, rather than assuming Heat Sword’s slams add Heat to its normal swings.

Common mistake

Do not read the Heat damage on slam attacks as part of every normal hit. The normal damage listing contains only Impact, Puncture, and Slash.

Limitations and tradeoffs

  • Normal hits emphasize Slash but have a 5% critical chance.
  • Heat damage appears in the slam modes, not the listed normal attack.

Common mistakes to avoid

  • Assuming normal attacks deal Heat because the weapon is named Heat Sword.
  • Combining slam damage with the normal attack’s listed damage.
