Nightshade and Last Hope and you should be all set.

In addition to stats, armor provides mod slots to maximize how you want to play. First: [b]Stats[/b] These can be allocated as desired (and with available armor) and are as follows: [b]Mobility[/b]: [i]increases walk speed in all directions as well as increase jump height.[/i] - high mobility allows one to quickly sidestep incoming melee attacks and reach ledges at greater heights with ease. If you desire to move quickly even when not sprinting, put points in Mobility [b]Resiliance[/b]: [i]increases player health.[/i] - this stat only increases your [u]red bar[/u], or Health, and not your shields. Additionally, gives more health with the first 5 points. If you need to be able to survive one more shot more often, put at least a few points in Resilience. [b]Recovery[/b]: [i]increases rate of health and shield recharge as well as reduces delay until they begin recharging[/i]. - very useful to get back into the fight. Noticeably increased gains per point. If you don't like hiding behind rocks waiting for your shields to recharge, put points in recovery. [spoiler]My Personal favorite allocation is 10, 0, 5.[/spoiler] Second: [b]Mods[/b] There are three main groups: Stat Mods, Weapon Mods, and Ability Mods. [b]Stat Mods[/b]: these can allow you to maximize your stats as they will provide +1 Mobility, Resilience, or Recovery. - use these if your stats aren't quite where you want them to be. [b]Weapon Mods[/b]: these improve your weapons secondary stats-- handling, recoil, and reload. - use these if you want to improve a weapon's lacking stat or just want improved weapon performance. Take care to notice what [u]type[/u] of Weapon they affect as they are divided into Kinetic, Energy, and Power. - additionally, don't waste the mod or slot improving a weapon you rarely use or that doesn't need or can't use it. Swords don't need a reload mod as an obvious example. Here's where things get trickier. The above mods are good for any armor for any subclass. The following will only affect one subclass. [b]Ability Mods[/b]: these reduce the cool down of the indicated ability for the indicated element. They can stack up to three times and give up to 50% reduction in CD (as of latest patch) - use these to get the abilities you want to use more often. However, if there is an ability you don't (or for a specific activity, aren't going to) use, don't waste the mod and slot for it. [spoiler]For Nightstalker Specifically, I want my dodge and melee recharged asap, so I use those mods. Any other slots will be filled with stat mods as needed, and topped up with weapon mods as desired.[/spoiler] Hope this helps.

Helmet: Survivalist Masterwork with Resilliance Mod Arms: Survialist Masterwork Mod with Mobility Mod Chest: Heavy or Survivalist Masterwork with any Mod Boots: Mobile Masterwork with Recovery Mod Cloak: Masterworked with Mobility There are different combinations for this. This is for a 9-4-4 build. You will have to adjust the perks on the pieces of armor so you might have to play around with it.
