I don't play on PC, but I will give you a few tips.

With regard to your abilities, you are missing the two bread and butter abilities used by almost all nightblades in pvp. Get surprise attack and mass hysteria on your bars straight away. Mass hysteria can and should be used once every 4 seconds in a fight.

On your bow bar, draining shot doesn't tend to work well in pvp. I've tested it and it just doesn't fire, so I would swap that out for the jump back version if you're looking to gain range, or better still replace it with vigor.

You also need either shuffle or double take on your bar. You're missing 20% dodge chance, which is key.

I would suggest you scrap rending slashes for surprise attack and piercing mark for mass hysteria. That'll give you a strong melee bar. You want to light attack before each surprise attack for high speed dps.

Om your bow bar, draining shot switches for vigor. You need that heal. Especially if you're not going 2h, so have no rally (I prefer 2h as rally is just op). Retreating manouevor switches either for double take while is a speed boost and 20% dodge or shuffle which is 20% and removes snares.

Gear wise, there are a hell of a lot of choices depending on whether you want to be a ganker or prefer sustain. I'm not going to get into gear as there are so many choices for a stam blade. To get you started, I'd suggest you go copy one of Sypher'S builds. Google him.

Hope that helps a bit!

Piercing mark is a good ability. I do like it and will slot it if I'm fighting an annoying nb, but it doesn't quite make the cut for my main bar.

It sounds like you want to play more of a sustain style, so I'd recommend getting your health to about 21K. Slotting surprise attack and mass hysteria will instantly give you 6% more HP due to the passives, so that'll help.

You need to remember to play defensively, rather than all out attack. I run drinks which give stamina/magicka Regen, which really boosts sustain and means you have lots of magicka Regen for cloak and mass hysteria.

When you cloak, the passive will increase your resistances for a short time and dots won't tick on you in cloak, so you need to cloak a lot in combat. If you keep using mass hysteria your target will use a lot of stamina breaking free too.

The vice cannon set adds quite a nice heal if you're looking for a little boost, as you don't have rally. Cloak healing is quite important. Try and get some tri pots for Regen, as you haven't got much healing right now.

I have two set ups. I love my bow, so I play an unusual pure bow build sometimes. My build for that is 5 marksman, 4 morag tong, 1 kena and 1 bloodspawn. Abilities are poison injection, magnum shot, lethal arrow, mass hysteria, cloak and flawless dawn breaker with a 2h buff bar of relentless focus, vigor, magelight (for the empower passive for my first stealth lethal arrow which crits for about 12k), shuffle (this or double take you need that dodge chance 1 in 5 hits will miss you...), rally and consuming darkness, stack heals and fire your bow in safety of your 60% reduced damage ring.

My melee build is similar bow bar, except I switch magnum for vigor and hysteria for shuffle. The 2h bar is killers blade, ambush, surprise attack, mass hysteria, rally and incapacitating strikes.

Gear on melee set up is 1 kena 1 blood spawn 5 piece either vice cannon, hundings rage or vipers sting with ideally 3 agility and maelstrom weapons. Assuming you don't have maelstrom, you could go 4 morag tong, if you use one of the jewellery sets.

I play mainly solo and regularly win 2v1 and 3v1 fights with these builds, occasionally more if I can pick off 1 or two with my bow first.

Get yourself to 21K health in pvp. Either change your enchantments or stick some points into health, it doesn't matter which. Unfortunately you're going to be a bit squishy until you've got some heals. Rally is a great burst heal and gives major brutality. I'd recommend changing to 2h if you're not too in love with dw.

Hybrids don't really work. Take all of your points out of magicka and move them into health or stamina. The magicka/stamina drinks will sort you out for cloak etc. I use Rosy Disposition Tonic.

I would say push for vigor, rather than trying to go resto hybrid. You should be able to get vigor pretty quickly in pvp these days.

I don't have any points in magicka. You will see when you put on that Regen drink that you don't need it.

If you really like dw, you could always give up your bow for a 2h buff bar, similar to the one I mentioned above?

Good stuff. You'll not it procs on dots from stealth, so all you have to do is cloak then poison injection from cloak and the dot will stick.

Hi, yes, it is only available in medium. You get it from merchants in the Imperial City sewers. It will be for sale in guild stores too.

Ah, not sure if I can do it then, don't have IC. Any alternatives?
