SorceressTHIS BUILD GUIDE HAS 3 DISTINCT PROGRESSION 'VARIANTS':
1) Budget Hybrid Life/ES Setup
This first variant is meant for helping to gear starting in late act 3, which is the earliest you should consider swapping over to Warp. It will carry you through early maps quite well.
2) Chaos Inoculation Swap
This is also very budget, and is what you should be aiming to gear for while going through the map tiers. Once you hit around 4k+ energy shield, it's time to swap to this tree, to gain the benefits of immunity to chaos / poison / bleed damage.
3) HIGH BUDGET 10K ES Setup
You can start progressing to this immediately after the Chaos Inoculation Swap. Gear for it piece by piece. This just exemplifies what a well-rounded T15/T16 map farmer will look like.
HOW THIS BUILD WORKS:
Clearing
To put this very briefly, for generic mapping you simply 
Ball Lightning into packs of monsters and unleash 
Lightning Warp onto the balls inside the pack. You shotgun the pack and keep doing this to move forward fast and clear everything.
Difficult Single Targets (full bossing rotation)
Now, this clearing interaction also litters the floor with Lightning Infusion. For single target damage, the full rotation is
1) Sigil of power (from a weapon swap 
Chiming Staff
2) 
Elemental Weakness
3) 2x 
Orb of Storms
4) Ball Lightning Lightning Warp into the boss
5) refresh Orb of Storms when they run out
i recommend pianoing your hotbar and having the skills in the correct order so its brainless. realistically you dont really have to always do the entire combo but thats how you do the most damage
Lightning Conduit autotriggers, and if really only should proc on unique monsters which is fine. its a massive nuke. Try and make sure the boss has Elemental Weakness on him when your energy is almost at 100%.
PUT YOUR BALL LIGHTNING ON LEFT MOUSE BUTTON AND YOUR LIGHTNING WARP ON RIGHT MOUSE BUTTON. NOT THE OTHER WAY AROUND THANK ME LATER!
