Understand Fortifying Fire
Useful when…
- Recover a listed portion of shields on critical hits.
- Consider it with turret use that can produce critical hits.
Effect and trigger
The effect is triggered on critical hit. It replenishes 0.5% of shields at rank 0, 2% at rank 3, and 3% at rank 5.
Plexus fit and related mods
Fortifying Fire is a standard Plexus mod with Vazarin polarity, base drain 6, and maximum rank 5. Predator increases turret critical chance, which may support the critical-hit trigger. Waveband Disruptor gives turret critical hits a chance to ignore enemy shields. Defensive Fire increases maximum shields per enemy killed for a limited time and up to a listed stack cap; it does not list on-critical-hit shield replenishment.
Ranking and listed sources
The mod reaches rank 5. Listed step examples include 30 Endo and 1,449 Credits for rank 0 to 1, and 480 Endo and 23,184 Credits for rank 4 to 5. The final step raises the listed replenishment from 2% at rank 3 to 3% at rank 5. Supplied drops list Orm Gox, Orm Harpi, Orm Weaver, Elite Orm Harpi, and Elite Orm Weaver variants; these entries do not establish current availability.
Limitations and tradeoffs
- Shield replenishment depends on critical hits.
- The rank 4 to 5 step costs 480 Endo and 23,184 Credits for the increase to the listed 3% effect.
Common mistakes to avoid
- Treating the replenishment as unconditional shield regeneration.
- Confusing increased maximum shields with the on-critical-hit replenishment effect.
