Just wanted to share this build, which as far as I know is the only one in the league (I checked poeninja and haven't seen anything similar). It's based off of Peuget2's build using Ghostwrite and Esh's Visage.

It's expensive. Basically a Mageblood build using lots of mana reservation and minion damage to increase the explode damage via the annoint Spiritual Aid, which converts all minion damage to your generic damage. It uses the Redblade Gladius instead of a Bow so that we get extra added defense with a shield. We solve the mana issue of casting totems using inspiration and reduced mana cost flask, which brings the cost of casting totems to zero.

The build is very tanky, I've done all Uber bosses with this build. 100% delirius maps. 30 wave Simulacrum. Great at delve with permanent phasing with flask. Fast heist.

Build can do all map mods including no leech, no regen, reflect, etc

It can tank the Shaper Beam and Sirus's Die beam, Atziri's fire explosions.

The downside is that it's a slow mapper, the clear speed could be much better.

It's possible to build a similar build using an explode wand or sceptre, but damage would be half. Having the mageblood may bring the cost out of reach for some people.
