Understand Blade of Truth

Useful when…

  • Adding melee damage to the Jaw Sword.
  • Increasing the Jaw Sword mod’s listed Truth value.

At rank 0, Blade of Truth grants +25% Melee Damage and +0.3 Truth. At rank 2, it grants +75% and +0.8; rank 3 reaches +100% Melee Damage and +1 Truth.

Weapon and slot fit

This standard Rare mod is specifically for the Jaw Sword. It has Madurai polarity, base drain 4, and maximum rank 3, and occupies a standard slot. It should not be treated as a general melee mod for other weapons.

Fusion investment

Fusion costs rise with each rank: rank 2 to 3 costs 120 Endo and 5,796 Credits. The final step raises the listed melee damage from +75% to +100% and Truth from +0.8 to +1. Consider that step when both increments matter to your Jaw Sword setup.

Limitations and tradeoffs

  • Only compatible with the Jaw Sword.
  • The source names Truth without describing its effects.
  • The final rank costs more Endo and Credits than earlier steps.

Common mistakes to avoid

  • Equipping or planning it as a general melee mod for weapons beyond the Jaw Sword.
  • Assuming the Truth value has a particular effect not described here.
