Best 3.28 Endgame Atlas tree: Exarch or Eldritch Altars, Expedition and Scarabs.

BEST ATLAS for 3.28

Best Endgame Atlas for PoE 3.28 Mirage

This build is the definition of high risk, high reward: by taking Wrath of the Cosmos you need a strong character build to survive the intense damage scaling.

Scarabs and Shrines are the main mechanics this atlas focuses on, while enhancing smaller bonuses such as Altars that help your character significantly when clearing maps. Focusing heavily on Scarab nodes ensures a massive boost to your map loot and encounters with very low investment.

Shrines are one of the best mechanics to pair with this setup. They provide massive temporary power spikes and extra monster density, making it much easier to handle difficult, highly juiced encounters without slowing down your clear speed. The shrine buffs will easily carry you through the massive monster packs generated by your scarabs.

Both Eldritch and Exarch altars provide good currency/hr, it comes down to the player's preference: Eldritch influence has overall less chaos/hr ratio compared to Exarch's, that's why this atlas build focusses on red altars.

Disclaimer: this atlas tree demands a very powerful character build and is not safe for hardcore because the Wrath of the Cosmos and Eldritch Gaze encounters can get difficult.
