Ultimates: For you main ultimate you want to be using Incapacitating Strike, the bar you decided to put it on is your choice, some people put it on both bars. Otherwise, you can put Flawless Dawnbreaker on your other bar.
The key to Nightblades this patch is light attack weaving with Grim Focus, for Stamblades, that is Relentless Focus. This is a general rotation, the best results I have found on Stamblade, do not follow a set rotation, rather a fluid recasting of dots on cooldown.
Q: When do I heavy attack?
A: I replace surprise attack with heavy attacks as needed.
Q: When do I ult?
A: If in War Machine, on cooldown, otherwise, before the FIRST Relentless bow proc on your front bar, or when Endless Hail is at 4 seconds.
Race: The best race to go with an Aquity setup is Redguard, they have high max stamina pools and some stamina return. For non Aquity setups, Khajiit is the best option.
Food:Blue Max Health + Max Stamina.
Potions: Weapon Power and Weapon Critical
Weapons: If in aquity, one axe main hand, if not, two daggers.
Credits: I'd like to thank all my friends who have beared with me through the making of this Stamblade, more specifically, Rataroto and Nosferatu Zodd. I'd also like to thank iHobi for the parse submission you see above.
