FINAL FANTASY XV WINDOWS EDITION · Weapon: one-handed sword
Soul Saber
A one-handed sword with a damage bonus that rises as the wielder's stamina falls below half.
How it works
The table lists Soul Saber with attack 343 and +12 Max MP. Its damage bonus is +4% for every percentage point of stamina reduction under 50%. The weapon's flavor description also identifies greater striking force as stamina flags. The source gives no cap or additional activation condition beyond the stated stamina threshold and per-point scaling.
