 Stealth Attack Damage = Weapon Damage × Stealth Multiplier × Weapon Multiplier 
 * 3.0x Weapon Multiplier for Daggers, Dual Daggers, Polearms, and Staves.
 * 6.0x Weapon Multiplier for Hammers.
 * 4.0x Weapon Multiplier for all other weapon types.

if you go for Stealth Kills or even Fatal Teleport Ash ... just Take Arca Triton (with maxed attackspeed).

Even a Galatine Prime Fatal Teleport  deals 1.2Mio dmg on a Level 120 Grineer Gunner.

Picking a Dagger with this mod, is not worth it imo - you overnuke enemys with stealth attacks or Lethal blows anyway (except for ground finishers) but again... building a dagger for Groundfinishers is not worth it imo.
