Crafted gear is one of the best sources of endgame gear for Nightblades. At this point, crafted gear becomes more valuable, since gear lasts longer and becomes more valuable. Crafters make some of the best pieces of endgame gear. Make sure to join a crafting/trading guild or two where you can utilize the guild store and ask about purchasing upgrades, if you haven’t yet. Players need to join good guild for Nightblade.
When it comes to veteran rank gear, remember that the actual differences in DPS between one piece of gear and another are relatively minor. In picking up a piece of gear, remember that tit is more important to have the right enhancements for your build rather than a few extra damage numbers. That also means that when you indeed obtain some good veteran rank gear, you might not want want to change it until later. For example, you may not even need to replace an epic-quality weapon or pair of weapons at all until you reach VR10, if you happened to pick up one.
As far as enchantments and traits are concerned, make sure to have an idea of what you want when searching for ideal jewelry pieces or when requesting crafted gear. The baseline additions or attribute bonuses on gear are the enchantments. As a Nightblade, this is where you’ll mainly want to focus upon on resource management, just as mentioned above. What you should generally look or ask for is increased maximum Stamina or Magicka. A decent second is increased Magicka or Stamina regeneration.
Anything that will reduce the costs of block/bash, Health regeneration, and increased maximum Health is what you will want to look for as a tank. Depending on your build, you will have more choices when it comes to weapon enchantments, although one solid option is to go for magic penetration or armor penetration. Damaging proc enchantments on weapons are mostly not very good.
When it comes to Nightblade endgame gear, and as far as traits go, you will want to focus on two different traits:
Increased item enchantment effect for chest, head and legs, with an effect that stacks. To maximize the effect of your enchantments, these traits should be placed on all three possible items.
Increased Mundus Stone effect for all other armor slots, with effects that also stacks. An extremely important part of the game is the Boon (Mundus Stone) buff. Always have the best one available as this buff is permanent. In Cyrodil is where you can find all Mundus Stones.
If possible, you should also try and get the highest quality of items when you have crafted gear. Using rare components obtained by breaking down other items, crafters can improve the quality of items. By providing crafters with items to break down for improvement materials, you can often help them create an endgame set.
