WEAPON SET ASSIGNING:
To assign a skill to a specific weapon set, open the skill window and click the checkbox for the desired weapon set (both are checked by default).
At this stage of the build, 
Whirling Slash and 
Barrage should be designated to weapon set one, while 
Twister and 
Ice-Tipped Arrows are designated to weapon set two. All other gems can remain assigned to both.
More on how to assign weapons and passives to their preferred weapon set can be found in their respective sections of the guide.
ROTATION:
For maximum damage scaling, the rotation remains 
Whirling Slash > Whirling Slash > Whirling Slash > Twister and should include pre-casting both Ice-Tipped Arrows and 
Barrage, as well as a Dodge Roll with roughly 6-8 seconds passing between each 
Twister attack. Use 
Sniper's Mark whenever convenient. At this stage in the build, 
Parry gets dropped from the rotation.
JEWELLER'S PRIORITY:
The priority order for Lesser, Greater, and Perfect Jeweller's is as follows:
- Twister
- Ice-Tipped Arrows
- Whirling Slash
- Barrage
Herald of Ice
Wind Dancer
Vivid Stampede (and all other ascendancy notables) grants its max 5 sockets at character level 90.
SPIRIT GEMS:
195+ Spirit is needed to equip all of the Spirit gems in this setup, which requires all Spirit campaign quests completed, 
Beacon of Azis, a high spirit roll on the body armor, and a spirit reservation desecration mod on the 
Soaring Spear. If you fail to hit this mark, disable 
Berserk and assign 
Trinity to weapon set 2 only for the time being. Otherwise, Berserk is the only spirit gem designated to a specific weapon set, weapon set 2.
OTHER:
Whirling Slash should NOT be leveled up. It remains at level one to reduce the mana cost of the skill as much as possible. This is especially important in the later stages of the game.
Huntress
Spirit Walker
Primal Bounty and 
The Mhacha's Gift, giving Twister a huge boost to damage and clearspeed.
