Hey guys, with seeing this forum flooded with sub questions and there being mixed responses to these I thought it would be nice if we set up an initiative to get those answered. I myself do not have the answers for all of these so it's very much a WIP and will update it with answers / questions from the comments also feel free to debate on the answers made already.
Artifact & Talents
Q. How should I level my artifact
Sub MS & Sub OS
Finality>Akaari>Nova for Single-Target, Nova>Finality>Akaari for AoE
Q. What talents should I take
Weaponmaster, Subterfuge, Strategem, CheatDeath/Elusiveness (depends on fight), Prey on the Weak, Premeditation, Master of Shadows. DFA is better if 3 or more targets.
Rotation
Q. What is my rotation in ShadowDance
A. SS>SS>Finisher>SS>SS>Finisher is the general rotation. Which finishers you use depends on if you need to reapply Nightblade in pandemic range. You will want to refresh SoD during your dances too if it's in pandemic.
Q. How much energy should I pool before using ShadowDance
A. If you have the sub boots, 45+ energy. If not, pool to 55+
Q. On 2 Targets - what is my rotation
A. Keep Nightblade up on both targets and use Shuriken Storm for 2+ targets instead of SS or backstabs. If you have the Ravenholdt ring it's usually better to use Shadowstrike instead of Shuriken Storm at 2 targets.
Q. On 3+ targets what is my rotation
A. Same as above mostly, upkeep NB on priority targets that will live longest and shuriken storm>evis.
Q. What is the optimal opener
A. Symbols in prepull - SS>SS>SS>Blades>NB, after that you're just going through your dance charges doing the rotation.
Q. How does bloodlust affect my rotation?
A. It doesn't affect the rotation at all. However if you find yourself capped on energy you will want to backstab once before you next dance.
Q. When do I use Goremaw's Bite?
A. When not using Shadow Dance or Vanish, you have 2 or less combo points, and you have 50 or less energy
Q. What do I do after I run out of ShadowDance charges?
A. You will want to be pooling to 55 energy and backstabbing until 5-6 combo points then using a finisher during this phase. If you have Goremaw's or ShadowBlades coming up soon it can be really handy here. Eventually you will have 1 or more Dance charges. Use them as they pop up, but make sure you pool appropriately.
Q. Do I want to line up Shadowblades with Goremaw's?
A. It's usually best to just use both on cooldown. Goremaw's is an emergency energy/cp button, so it won't be used until you start to become starved on dances or energy.
Q. When should I vanish?
A. You use Vanish as a free dance charge, and want to use it when you have 2 or less dance charges available (if you have 3 dances ready use 1 dance instead). So you dance rotation is going to be Dance>Vanish>Dance>Dance in that order.
Legendary Rotation
Q. How does my rotation change with the Legendary boots?
A. Only have to pool to 45+ energy
Q. How does my rotation change with the legendary cloak?
A.
Stat Priority
Agi / Mastery > all for the most part. Sim your character to properly find results
