Immortal Star Upgrade Costs

In this article we shall dive into the fundamentals of Immortals – their fragments. These fragments are what allow you to unlock the Immortal and are required in abundance in order to upgrade your immortal with Star-levels (cap lvl 7).

These levels are super important, not only because they give the Immortal new power boosts, but most importantly because you unlock 3 passive-slots and an artifact slot on your immortals as you progress through the star-ranks (read about artifacts)

  • 1st passive slot requires 3 stars
  • 2nd passive slot requires 5 stars
  • 3rd passive slot requires 7 stars
  • Artifact slot requires 120 fragments AFTER 7th star has been unlocked

Upgrade Stars – Immortal Fragments Required

The requirements in terms of Fragments to upgrade an Immortal’s Star Rank is very different based on the rarity of the Immortal in question. With the added new Quality Chaos (as of patch 2.4 with Loki and Wokung) we now have five tiers of quality.

Below you will find a table of the required Framents for each star level.
