How to grind 101

Yes, i'm only gonna dedicate a single section to this, no point in going extremely in-depth on it, I'll try to keep basics as simple as possible, so even a new player can understand, once you get proficient with the spec, you can tailor the combo to suit your own needs, depending on the spot you're grinding.

For PvE, what we can basically do, is split our PvE skill rotation into 3 sections, and connect them in right order, once you get more proficient with skill flows, you can make your own combo while keeping logical skill order (like obviously, you don't want to -DP debuff mobs at the end of the combo or use the skills with highest single skill damage at the beginning), and while keeping in mind addon up-time sustain.

Scars of Dusk rotation: Counter > Severing Thrust > Counter > Scars of the Dusk

S+LMB > Shift+LMB > S+LMB > C

Note: I always open my combos with this, it allows you to quickly cast 3 skills which means you can proc 6 addons total + Scars is 16AP buff, maximizing the DPS output for the rest of the combo, you can also use Solar Flare before or after scars to proc 2 additional addons, if you use it before, it flows into Scars of Dusk naturally, and if you use it after, it flows into Jump Slash

Ling crit rotation: Spinning slash > Jump Slash > Ground Slash - Heavy Strike 3x (Or any of the lingering crit combo variants from the section earlier)

S+RMB(Hold) > S +E > LMB+RMB

Note:  Heavy Strike 3x means that you do the full skill, so all 3 slashes.

Finishers: Ground Smash > Earth Tremor / Seismic Strike >  Dusk Slash

Shift+F > Shift+F / Shift X + LMB

This is a simplified explanation on how combo'ing works on succession in PvE, it should be easy to digest if you're only starting to learn the class, once you learn the ropes, i recommend watching my video on  BiS PvE combo:

Succession Warrior High-End Infinite PvE Combo

Combo:

Ground Slash - Solar Flare - Severing Thrust - Counter - Scars - Spinning 2x - Ground slash - Heavy Strike 3x - Counter - Ground Smash - Earth Tremor - Seismic Strike - Dusk Slash - Shield Charge - Counter - Severing - Counter - Scars - Spinning 2x - Ground Slash - Heavy Strike 3x - Counter - Ground Smash - Earth Tremor - Spinning 2x - Ground slash - Heavy Strike 3x - Counter - Severing Thrust - Counter - Scars - Seismic Strike - Dusk Slash - Shield Charge - Counter - Spinning 2x - Ground slash - Heavy Strike 3x - Counter - Ground Smash - Earth Tremor 

Note: This is literally best possible combo you can do for PvE, unless you're pushing for numbers on spots like DSR, you don't have to go this hard

Pack to Pack movement

For pack to pack movement, what you usually want to do is just spam Forward Slash and Charging Thrust, and what you can do to engage pack, is use any of the Solar Flare flows, usually Jump Slash or Scars of Dusk, then the rest of your combo the way you see fit.

What you can also do, is chain skills in a way that will allow you to pass through the pack without collision by utilizing Earth Tremor (Leap), to get back attacks from the beginning of the combo, the way you do it is:

Shield Charge > Quick Counter > Earth Tremor > Rest of the combo

W+RMB > S+LMB > F > Rest of the combo

Solar Flare > Chopping Kick > Quick Counter > Earth Tremor > Rest of the combo

W+C > S+F > S+LMB > F > Rest of the combo

• Scars of Dusk: +Movement Speed / -DP

• Severing Thrust: Back Attack Dmg / Crit Damage

• Heavy Strike: +DP / Crit Damage

• Spinning Slash: Crit Rate / +Attack Speed

If you manage to get a catch from distance:
