Biotic Rounds

AX-52 conditional damage and status mod

Released Feb 6, 2025

Biotic Rounds temporarily adds Viral and Magnetic Damage and Status Chance to the AX-52 after a weak point kill. Consider it when you can reliably land that trigger and make use of the 15-second window.

Biotic Rounds GUIDE

Understand Biotic Rounds

Useful when…

  • AX-52 builds that regularly secure weak point kills.
  • Adding temporary Viral and Magnetic Damage and Status Chance after the trigger.

Trigger, effects, and duration

A weak point kill grants +25% Viral and Magnetic Damage and Status Chance at rank 0, +100% at rank 3, and +150% at rank 5. The bonus lasts 15 seconds. A weak point hit alone does not satisfy the stated kill condition.

Weapon and slot fit

This standard Rare mod is compatible with the AX-52, has Madurai polarity, base drain 2, and maximum rank 5.

Rank investment

The rank 2 to 3 step costs 120 Endo and 5,796 Credits; rank 4 to 5 costs 480 Endo and 23,184 Credits. Higher rank increases the damage and Status Chance bonus, but the effect remains conditional on a weak point kill. Consider the higher ranks if you can consistently activate the timed benefit.

Limitations and tradeoffs

  • Requires a weak point kill to activate.
  • Its bonus lasts only 15 seconds and is specific to the AX-52.

Common mistakes to avoid

  • Assuming a weak point hit without a kill activates the bonus.
  • Treating the listed bonus as a permanent AX-52 stat increase.
