What should I put my Stat points in?

Chieve

I made a night blade for his sneaking feature, and I wanna be able to kick ass (especially in PvP but also in PvE when time comes)

I found night blade to actually have all the abilities I think I need, without dual wield, but I decided to go into dual wield anyways.

So most of my points are in stamina, but considering the fact most nightblade skills use magicka, should I just use that or no?

(Sorry my phone won't let me edit...)

Also o wanna mention the class abilities look more applealing...should I only use dual wield for passives or what?

Some Nightblade abilities can be morphed into a stamina version. Knowing that, yes just keep putting points into stamina if stamina is the way you wanna go as it will increase your damage. Maybe put some into health as you level up.

Stamina is also needed for stealth. Not only can you morph skills to use stamina or magicka but you can use enchants and consumables to take care of whatever your build is missing. I've been heard stamina Nb are very powerful. Stack stamina, use enchants n stuff to buff your magicka/health.

Stamina NBs are great for DPS. Definitely drop most (if not all) your attribute points into Stamina; skip Magicka entirely if you're a stamina build. A lot of NB skills have stamina morphs, so you'll definitely want to unlock all of those. DW is a great choice that works well with this class; a lot of the DW abilities can be skipped, but the two you most definitely will want to use/try are Steel Tornado (morph of Whirlwind) and Rapid Strikes (morph of Flurry). The Steel Tornado morph of Whirlwind is an amazing AoE with a killer radius and the Rapid Strikes morph of Flurry is a great armor debuff and single-target damage skill.

Here's a link to webpage showing all the NB abilities per tree and their available morphs so you can see which ones will scale with stamina:
