My main is a Fed and I'm starting out a new Klingon alt. It's been a long time since I had a starter character. My new KDF is an engineer in a BoP. I'm wondering what the best set, or gear, would be to level my KDF character. I'm almost through with the story line missions so I've got Jem'Hadar Mk X and Breen Mk XI.

I'm looking for the best setup to run ESTFs. Ultimately I want to get KHG Deflector and Engine with Assimilated shield (I think). Should I use Jem'Hadar, Breen, or go back and replay the episode missions for other gear?

Of the mission sets you can get, Jem'Hadar Mk XI is most end-game worthy, particularly if you drop the deflector for a nice Positron one for added survivability. The Reman shield from Coliseum can be gotten at Mk XI if you redo the mission if you like Covariant shields.

You could also grab Mk XII standard gear off the exchange. Mk XII gear like Sheilds and Deflectors don't go for much more than scrap value currently, so picking up Mk XII [cap][res] shield of your prefered type might be a good way to transition.

If you're willing to throw down the Dil for it, the Advanced Fleet gear is decent enough for ESTFs, and Elite is usually even better if your fleet has access to it(close enough that you may not need to transition to STF sets).

I'll second the Jem'Hadar set. It's quite nice, especially if you use polaron. I've used it in ESTFs with great success.

Jem engine and shield are solid, maybe swap in a Positron deflector. Alternately, positron deflector, Efficient Impulse Engines from "Second Star To The Right," and a Resilient shield with [cap] [pla].

Also don't forget some kind of kinetic armor, either Neutronium or Monotanium. Plasma burns add up, but its the kinetic impacts that are the real killer.

Thanks all. I got 2 Neutronium armor consoles and I think I'll go back and get the Jem"hadar Mk XI set.

Jem'Hadar Mk XI set with Polaron weapons and Polaron Phase Modulator tactical consoles is hands down the best set to start doing ESTF missions. You should use at least 1 Monotanium Alloy and 1 Electroceramic Hull Plating armor consoles. Adding a Neutronium Alloy console is also good.

I've never used Polaron weapons I don't think. Hadn't even thought about them. But, the 2-piece bonus does boost polaron weapons doesn't it?

Yes it does increase Polaron damage.

I'd recommend the jem set as well... though it really depends upon build.
an often over looked set is the aegis set too, albeit for certain builds.

^That, with the a combination of +shield systems and +sif on the positron array. One of the better combinations for endurance, without spending dil.
