This is an all-purpose [Wisp] build.
It will take you through Steel Path without many problems as long as you know how to use her. Let's see step by step.
With this in mind, now let's move to the build itself:
Duration. We need some because it will make our reservoir buffs last longer when we're not near a plant. It also makes enemies blind for longer, which is also helpful.
Strength is the main stat here. Higher strength means higher reservoir buffs but also higher damage from Breach Surge. We need it high here.
Our efficiency is low here, so we need a good energy pool (Primed Flow) and some good means of recovering energy: Energize.
The health will be increased by our reservoirs so we don't need to get a slot for it.
Instructions
Cast your reservoirs first. You want all 3 active at every moment. Health, speed and light CC with the shocks.
When surrounded by enemies, use Breach Surge and start dealing damage, the sparks will jump from one enemy to another and you will be killing things that you didn't know they were there. Refresh Breach Surge often!
Remember that using Breach Surge to teleport to a reservoir will also double the range of the surge, affecting much more enemies, and if you use it with a will-o-[Wisp] active, the copy will also cast it! Learn these sinergies quickly and you'll be dealing insane amounts of damage while also helping your party!
Pillage is a very nice addition that will increase your party shields and will also strip armor and shields from enemies. Use it frequently.
