Galvanic Field AOE/Mana stacker

https://pastebin.com/tdnWMUhD

Sharing my latest build and hoping someone will see some improvements that can be made.

Galvanic field has some downsides: Low AOE and poor hit rate.

We get around the AOE by slotting a Phantasmal GV into a Crest of Desire, and Scaling mana with Heirophant. This gives GV domes usually a couple of screens of area. The beams fire from the centre of the dome and dont go through walls or obsticles, so open maps work better.

GV can fire 10 times per second but only hit the same enemy twice per second, and these cannot be scaled up. We can improve the clear by taking the +1 chain mastery, but the single target is still pretty bad. POB says 2.2M single target, but that's with everything up and assuming 75% shock.

Cost about 100 chaos to get going, spend another 3 Div upgrading to 6L, Watchers Eye and jewelery catalysts. Running T16 maps no problem, even map bosses go down easy enough. No chance with pinnicle bosses, let alone ubers.

Usually I dont mind plodding around maps, but some more move speed would definately help with manouverability in boss fights and sanctums. Chaos damage is kind of dangerous if mana falls low and coruscating potion is not up. And of course ele reflect is bad news.

Pretty fun and easy playstyle, and with the MTX GV looks pretty badass.
