What are Random Immortal Fragments?

Understanding Random Immortal Fragments in Infinity Kingdom

Random Immortal Fragments are basically IK’s off-brand Philosopher Stones — but honestly, they’re way better for most players because the pools aren’t limited to a specific list of select few immortals like the Halls is. Instead, you gather 60 fragments of a type, and boom: you summon one random Immortal from the associated pool.

The best part is that these pools cover almost all Immortals, including expensive heavies like Baldwin, Genghis Khan, and paywalled immortals like Zenobia, Himiko, etc. So even a low spender or free player can pull immortals that used to be locked behind pretty rough paywalls.

There are ten kinds of Random Immortal Fragments, each tied to a specific pool of immortals.

The 10 Types of Random Immortal Fragments

Fragment TypeWhat It SummonsNotes
Random Epic Immortal FragmentsAny Epic Fire, Water, Earth, Lightning, or Wind ImmortalVerified by testing: no Holy or Shadow included. Premium Epics (Baldwin, Genghis, Zenobia, etc.) are in the pool.
Random Holy Immortal FragmentsAny Epic Holy Immortale.g., Theodora, Manco, Gilgamesh.
Random Shadow Immortal FragmentsAny Epic Shadow ImmortalBathory, Himiko, Bjorn, etc. (Flavius excluded since he’s not Epic.)
Random Holy/Shadow Immortal FragmentsA random Holy or Shadow ImmortalMixed pool. No bias confirmed toward either side.
Random Chaos Immortal FragmentsA random Chaos ImmortalVery slow to collect. Pool probably excludes the very newest Chaos release temporarily, but this is unconfirmed and cannot be treated as fact.
Random Fire Immortal FragmentsAny Fire ImmortalElement-locked.
Random Water Immortal FragmentsAny Water ImmortalElement-locked.
Random Earth Immortal FragmentsAny Earth ImmortalElement-locked.
Random Lightning Immortal FragmentsAny Lightning ImmortalElement-locked.
Random Wind Immortal FragmentsAny Wind ImmortalElement-locked.

The Data Project: Helping the Community Map Drop Chances

The community needs you! Right now, the actual summon odds for these fragment types are unknown. IK never releases the internal gacha weights. So the only way to figure out the real probability distribution is for the playerbase to log every single random fragment summon we can get our hands on.

A group of us has already started a big shared sheet to record summons across:

  • Random Epic
  • Element-specific
  • Holy
  • Shadow
  • Holy/Shadow
  • Chaos (when someone actually gets enough…)

This is the only realistic path to uncover how weighted the pools are, and which Immortals show up more often.

👉 If you want to help the community reveal the true drop rates, please join the shared Google Sheet and log your summons.

The more data points we collect, the more accurate the drop-rate estimates becomes.

Quick overview on how to Collect Random Immortal Fragments

Golden Pass

Still the most consistent source for newer players:

  • Random Epic
  • Elemental random fragments

Honestly, this is the backbone for most people’s early and mid-game fragment collection.

Seasonal Events

You’ll see many types of random fragments there – even chaos!

Harbour (long-term grind)

The Harbour drip-feed is slow but steady:

  • Early levels → Random Epic
  • Mid → Holy & Shadow
  • High → Chaos

Why These Fragments Actually Matter (Player Perspective)

So here’s the real talk — and this is the stuff players feel immediately in their account growth:

1. They give free-to-play and light spenders access to premium immortals

Back when the game launched, guys like Baldwin, Genghis Khan, Zenobia, etc. were entirely paywalled and spend-to-collect.

Now? A random Epic or element fragment can legitimately pop one of these. And the same is true for holy, shadow and even chaos! Insane compared to how expensive it was to get these back in the day.

This changes the entire power curve for F2P players — you can actually build full meta marches just from fragments and events.

2. They massively improve your Soul Crystal income

And this part is huge but many players overlook it. Every time you pull a duplicate you don’t need, you melt it in the Alchemy Lab → purple crystals (Soul Crystals). And those Soul Crystals go into your Tower of Knowledge skill upgrades (which are insanely expensive long-term).

Your ToK growth rate can be a very big bottleneck in the game, and these fragments help you push through it.

Conclusion Summary

Random Immortal Fragments aren’t just a fun gacha mechanic — they’re legitimately one of the most important progression systems in the entire game now. They let every player, from F2P to whale, access strong immortals, build Soul Crystals faster, and grow their roster without being tied to Philosopher Stone banners or paywalls.

Bottom line: Collect every random fragment you can. Always melt your dupes. And please log your summons in the shared sheet — the more data we have, the faster we crack the real drop rates.
