Necrophagic Vigor

Hema critical-stat augment

Released Oct 23, 2025

Necrophagic Vigor grants Hema critical chance and critical damage when reloading, in exchange for draining health based on the ammunition created. Consider it if that conditional offensive bonus fits your Hema use and health-management approach.

Understand Necrophagic Vigor

Useful when…

  • Consider it for a Hema setup where reload-triggered critical bonuses are useful and the health cost is manageable.

Reload condition and health cost

Reloading drains up to half your Health based on the ammunition created. For every 20 Health drained, the mod grants a bonus to both Critical Chance and Critical Damage. At rank 0 that bonus is +10% per 20 Health drained; at rank 3 it is +16%; at rank 5 it is +20%. The total is capped at 360%.

Rank and mod fit

This standard Hema mod has Madurai polarity, base drain 2, and maximum rank 5. Fusion examples include 30 Endo and 1,449 Credits from rank 0 to 1, 120 Endo and 5,796 Credits from rank 2 to 3, and 480 Endo and 23,184 Credits from rank 4 to 5. Higher ranks increase the bonus gained per 20 Health drained, while the stated 360% cap remains. Weigh that improved rate against fusion costs and the health drain tied to reloading.

Practical limitation

The bonus is linked to reloading and health drained, so it is not described as a permanently active critical-stat increase. Health cost varies with ammunition created, and the input does not define the detailed calculation. Do not assume a reload always reaches the cap or costs exactly half your Health.

Limitations and tradeoffs

  • Reloading trades health for the critical bonuses.
  • The actual health drain depends on ammunition created; the precise calculation is not specified.

Common mistakes to avoid

  • Treating the critical bonuses as always active rather than tied to reloading and health drained.
  • Assuming every reload grants the maximum 360% bonus or has a fixed health cost.
