I created this unique build last league, cleared all content including ubers, nothing much changed apart from losing access to charms.

This build is similar to regular EA ballista Elementalist, but incorporates Golems, Eternal Damnation and Transcendence for tankiness.

We use trancendence to make our armor also apply to some of elemental damage from hits,

We use Trancendence to make armor mitigate ele dmg from hits instead of phys dmg from hits,

We use Loreweave to counter the -max res from these two,

and scale golem effect, mainly Chaos golem to gain pure Phys dmg mitigation, since we no longer get phys mitigation from hits from armor. In adition we scale most other golem effects such as Accuracy and crit chance (Ice golem), Attack speed (Lightning golem) and Life regen (Stone golem), which all benefit our build.

You can start as normal EA Ballista elementalist untill you farm enough currency for the 4 Primordial jewels, which shouldn't be too expensive, golem builds are pretty much non-existent and I believe delving will be quite popular this league.

The PoB is very comprehensive, has multiple Gem, Gear and Tree sets for various stages of the league, has a detailed Notes section with EVERYTHING explained, and a crafting section for all the gear.

Also make sure to watch the video guide for the build's showcase and explaination (Timestamps in the description).
