Whether you’re upgrading characters, enhancing Light Cones, or progressing through the Astral Express journey, understanding how to efficiently farm and utilize Aetherium can make or break your interstellar adventure. This comprehensive guide dives deep into everything you need to know about HSR Aetherium—from acquisition strategies to smart spending tips—ensuring you maximize your gameplay with this indispensable currency.

What Is Aetherium in Honkai: Star Rail?

Aetherium is a premium in-game resource used primarily for:

Character Ascension: Unlocking higher level caps and stat boosts.
Light Cone Enhancement: Powering up your equipment for battle advantages.
Trailblaze Power Replenishment: Refueling energy to farm other materials.

Unlike Credits or Stellar Jades, Aetherium is specifically tied to progression systems, making it a non-negotiable asset for mid-to-late game content.

Simulated Universe Runs: Clear higher difficulty tiers for 300-1,200 Aetherium per run. Prioritize Elite and Boss encounters.
Event Participation: Limited-time events often distribute Aetherium as milestone rewards. Never skip these!
Memory of Chaos: Endgame players can earn 600 Aetherium per stage cleared bi-weekly.

Smart Aetherium Management: 2 Golden Rules

Avoid waste with these strategic principles:
