Hey I would just like to share my stam dk build and it has worked out really effectively for some time.
Skills
Sword and sheild - piercing armor, envasion, defensive posture, unstable flame , burning embers / ferocious leap
Bow - Green Dragons blood, igneous sheild, elusive mist, poison injection, magnum shot / any ultimate
So first of let's start with my sword and sheild . I did play with 2h and I loved it but I love the survivability and sustain of the sword and sheild . I chose piercing armor because not only does it apply major facture but also reduces spell resistance ; chose this because Dk are good in small groups and if you run with a friend's who is magika based this can help them debuff a target. Also this ability with high weapon damage can do around 4-5 on a non critical and the cost is close the nothing. Next I have envasion and this is because I love the farther you are the longer the stun , while critical rush might do more damage I feel like envasion has more utility.As for defensive posture I felt like reflective scales was to high a cost for this build so I felt defensive posture was better also because it was cheaper and stamina based. As for the next 2 abilities these are great dots and very cheap. Now the ultimate I found most effective was ferocious leap because it is cheap and the damage sheild is just great , you will also get some resources back from battle roar even though it is magika based.
Bow- Now some people might not think that putting Green dragons blood on the back bar is a good idea but after playing with it there for a while I found it just as effective. I also chose green dragons blood over coagulation blood because Green dragons blood also has the stam regeneration , this does stack with stam regeneration drinks as well. Next is the igneous sheild and you can make a great combo out of this if you apply igneous sheild then green green dragons blood. This ability also helps with the fact that Dks are good in small groups because this sheild also apply to your allies. For this build I am a vampire but it is not necessary but I like the mobility that elusive mist gives you . As for the bow abilities poison injection is a great dot and damage dealer to low health targets and magnum shot is a good stun / combo ability with any gap closer.
Gear- I wear 5 hundings rage and I do this because it is a great set and the passive for medium armor agility gives me weapon damage for a 5 piece set or more so by doing this I am just maximizing my weapon damage. I also wear 3 shadow walker jewelry and 3 night silence 4 with sword and shelid. There are many other gear sets and skill you could possibly use but thus is what I prefer and what has been working so thanks for reading hope you liked it thanks
