Covert Lethality

Covert Lethality is a mod that increases the base combo count of single daggers and deals double damage on finishers.

It can be used on the following weapons:

Stats

Rank	Initial Combo	Finisher Damage	Cost
0	+4	25%	10
1	+8	50%	11
2	+12	75%	12
3	+16	+100%	13

The "Initial Combo" bonus provided by this mod adds a flat number to the combo counter. When the combo counter is reset, either by using a heavy attack or through combo counter decay, it will reset to a minimum of this number.
Aside from Stealth attacks, the following Warframe abilities can also leave enemies vulnerable to melee finishers, regardless if the finisher is performed in front or behind the enemy;
- Ash's Teleport. (Even better when used with the Fatal Teleport augment.)
- Banshee's Savage Silence augment.
  - Savage Silence is required to make Silence open enemies to finishers, as the standard stun performed by the ability does not do so.
- Baruuk's Lull
- Equinox' Rest.
  - As any damage affected targets receive will make them fall to the ground, try to avoid attacking them if you plan to make use of Covert Lethality.
- Excalibur's Radial Blind (power only, the slide attack Radial Blind from Exalted Blade does not open enemies to finishers).
- Gara's passive Glint may blind enemies when she is in bright light.
- Inaros' Desiccation.
  - Do note that enemies are only open to melee finishers if they are facing Inaros when Desiccation is cast.
- Ivara's Sleep Arrow.
- Mirage's Prism.
- Valkyr's Paralysis.
  - It is not advised to equip the Prolonged Paralysis augment, as it instead leaves enemies vulnerable to ground finishers.
- Wukong's Cloud Walker.

Prior to Update 26.0 (2019-10-31), the mod possessed a unique mechanic called Lethal Damage, which refers to the ability to instantly kill an enemy upon performing a finisher attack regardless of their level or defenses.
