Understand Covert Lethality
Useful when…
- Increasing finisher damage on a melee weapon.
- Adding initial combo without relying on building combo first.
Effects and equipment
At maximum rank, the mod grants +16 initial combo and +100% finisher damage. Rank 0 grants +4 initial combo and +25% finisher damage; rank 2 grants +12 and +75%. It is a standard-slot melee mod with Madurai polarity and base drain 10.
Ranking investment
This mod reaches rank 3. The last step, 2→3, costs 120 Endo and 5,796 Credits, gaining four initial combo and 25 percentage points of finisher damage from the rank-2 values. Since the mod's drain is 10, include its capacity cost when deciding whether both bonuses justify a slot.
Related combo options
Corrupt Charge offers +30 initial combo with -50% combo duration; Galvanized Reflex offers heavy-attack efficiency and gains initial combo on melee kills, stacking up to four times. Blood Rush instead adds critical chance that stacks with combo multiplier. These options address combo or critical scaling differently and do not provide Covert Lethality's finisher damage bonus.
Acquisition
The supplied sources list Spy mission Rotation C rewards and several Duviri Endless reward tiers as possible sources. The listed chances vary by location and rotation; they do not ensure a particular result.
Limitations and tradeoffs
- Uses a standard melee slot and has base drain 10.
- Finisher damage benefits only when dealing finishers; initial combo alone may be the more relevant bonus for other setups.
Common mistakes to avoid
- Treating the finisher bonus as a general melee damage increase.
- Ignoring the -50% combo duration attached to Corrupt Charge when comparing initial-combo options.
