Teh Har'pen has some special attributes that make up for the lack of Torpedo skills. The first is the that is does a great deal of damage The second is the initial explosion is an Aread of Effect . The third effect is a minor damage over time effect. And then the 4th thing is a secondary high damage explosion which damage the hull directly which is an Area of Effect as well.
Baically you got a cross between Torpedo High Yield and Torpedo Spread w/o having to have those Tactical Abilities.
In that mission, you fly a Klingon ship that is equipped with that torpedo launcher. You uncover the plot and another Klingon helps you, then they arm that ship with the torpedo so you can fly in and out with a ship that has great turning. Otherwise you would probably die a lot..lol.
I been wondering, does the radiation DoT stack like plasma fires thus worth getting two for my cruiser or am I better off with two different torps?
Just so you know, the Har'pengs have a 10 second global cooldown. So you won't get that much stacking. But getting two for Cruiser isn't too bad a loadout. Depending on who I'm fighting I'll use 4x Quauntum or 2x Har'pengs and 2x Quauntums.
