Remnant 2 Prism Guide — How the System Works, Fusions, Legendary Perks and Rerolls

The Prism is Remnant 2's endgame power system, added free with The Dark Horizon update (September 24, 2024). It replaced the old relic-fragment grind: instead of three random fragment slots, you level a single item with five enhancement slots, merge compatible stats into Fusions (up to four, letting five slots hold nine stats' worth of power), and at max level pick one of 40+ Legendary Bonuses — effects like "your grey health can't be removed" or "all skill cooldowns halved." Prisms are the difference between a good build and an Apocalypse-clearing one, and this guide covers every piece: how to get all seven, how leveling and fusions work, the legendary perk pool, rerolling, and the fastest ways to level one.

What Is the Prism System?

Per the Remnant 2 Wiki's Prisms page: "The Prism system is one of the biggest buildcrafting additions in Remnant 2. It replaces the old Relic Fragment system with a much more powerful and customizable option."

The mechanics in one block:

• A Prism has 5 enhancement slots, filled as it levels by choosing 1 of 3 random stat options each time.
• When two compatible stats reach a high enough level, they merge into a Fusion — one slot holding both effects (e.g. Health + Stamina become "Hulk"). Maximum 4 fusions per Prism, for nine fragment stats in five slots.
• At level 51 the Prism grants a Legendary Bonus — pick 1 of 3 random capstones from a pool of 40+.
• You can influence the RNG by feeding specific Mythic relic fragments into the Prism early; the wiki and GameRant both confirm this shifts your level-up options toward the fed stats.

It's free for everyone — the Prism system shipped as part of the free update alongside The Dark Horizon, so you don't need any DLC to use it (owning the DLC just adds more ways to farm XP for it).

How to Get All 7 Prisms

There are seven prisms, each tied to one of the seven deadly sins. They function identically — the differences are purely cosmetic — so you really only need one to start.

The Prismatic Stones for the Jealousy craft are found by using a charged shovel attack at specific spots across the worlds. For most players the route is: buy Lethargy (1,000 Relic Dust), then let Voracity (world boss kills) and the Boss Rush prisms come naturally — the Boss Rush grinds are long-term goals, not something to rush.

How Prism Leveling Works

• Prisms gain XP from normal gameplay — kills, bosses, and especially Boss Rush mode.
• Level-ups offer 1-of-3 stat options; pick what you planned for, and avoid locking in stats you don't want (they consume slots).
• Fusions appear when two compatible stats are both leveled high enough (community testing puts it around level 5+ per stat pair). You don't need to "do" anything — leveling the pair automatically offers the fusion option.
• A full Prism needs roughly 617,500 XP per the wiki.gg breakdown — that's the whole reason fast-leveling methods matter.
• Feeding Mythic fragments early weights future rolls: rest at a World Stone on Apocalypse difficulty, then buy high-tier fragments from Dwell, and feed the ones matching your target fusions.

Prism Fusions — the Fixed Pair List

Fusions combine specific fixed pairs of stats — the wiki's example names are Hulk (Health + Stamina), Gunfighter (Fire Rate + Reload Speed) and Longevity (Mod Duration + Skill Duration), and the full datamined list is on the Fextralife Prisms page. Because the pairs are fixed, planning is simple: pick four pairs that match your build, feed their fragments, and let leveling merge them. Four fusions + one "dangle" (a stat you keep un-fused) is the standard perfect-prism recipe the community settled on — the Reddit buildcrafting guides all converge on this "four fusions + one filler slot" shape.

Legendary Bonuses — the Level-51 Capstone

At level 51 you choose 1 of 3 random Legendary Bonuses from a pool of 40+. Community-highlighted examples include:

• Unbreakable — grey health can't be removed (huge survivability).
• Unbridled — all skill cooldowns reduced by half.
• Steel Plating — +150 armor.
• Traitor — maxes out your core traits.
• Soulmate — +1 summon limit.
• Vaccinated — immune to negative status effects.
• Wrecking Ball — +100% explosive critical chance.
• Speed Demon — maximum movement speed bonuses.
• Spectrum — bonuses based on the colors of fragments in the Prism.

If you don't like your three options, reroll the legendary only (details below) — you don't lose the Prism, only the last level. The perfect-leg item for most builds is one legendary that multiplies your core loop, which is why rerolling is a real endgame activity.

Cleansing and Rerolling (the "Legendary Perk Reroll")

Two separate resets exist, and people mix them up:

1. Cleanse (full reset) — available once the Prism is at least level 10. It wipes the Prism's progress and its attached fragments (your relic fragments are kept) so you can rebuild from scratch. Use this when you scuffed the stat rolls before level 51.
2. Reroll the Legendary Bonus — at max level, if the level-51 legendary isn't what you wanted, rerolling regresses the Prism one level; you then re-earn ~50,000 XP to hit 51 again and get a fresh 1-of-3 choice. This keeps your fusions and stats intact — it's the "prism legendary perk reroll" everyone searches for, and it's the intended long-term grind.

Fast Prism Leveling in 2026

Boss Rush is the answer — it was designed as the XP engine for the Prism system. The free update's initial XP bonuses were buffed a week after launch (Veteran +5%→+10%, Nightmare +10%→+25%, Apocalypse +15%→+50% per the official patch), making high-difficulty runs the fastest way to farm Prism XP. Practical tips:

• Run Trial by Fire or The Gauntlet on the highest difficulty you can clear — more bosses = more XP per run.
• Combine with Explorer (Swiftness + Lucky perks) if you want faster clears; combine with a Medic/Hunter burst build if you want speed kills. See our Remnant 2 builds guide for loadouts.
• Boss Rush also drops gear you missed from the base game, so it doubles as loot farming — details in our Remnant 2 DLC guide.

Frequently Asked Questions

What is a Prism in Remnant 2?

The endgame progression item added free with The Dark Horizon update. It has five enhancement slots, supports up to four fusions (nine stats), and grants a Legendary Bonus at level 51.

How do I get a Prism in Remnant 2?

Easiest: buy the Prism of Lethargy from Dwell in Ward 13 for 1,000 Relic Dust. Alternatives: world-boss drops, Cass's shop, or the 50/200/500 Boss Rush completion prisms.

How do Prism fusions work?

Two compatible stats that both reach a high level merge into one slot. Pairs are fixed (Hulk = Health+Stamina, Gunfighter = Fire Rate+Reload Speed, etc.), max four fusions per Prism. Feed matching Mythic fragments to make the right stats appear.

How do I reroll a Prism legendary perk?

At max level, rerolling regresses the Prism one level; re-earn ~50,000 XP to hit 51 and pick again from 3 new legendary options. Your fusions and stats are kept.

How long does it take to max a Prism?

A full Prism needs roughly 617,500 XP. Boss Rush on higher difficulties is the fastest source — expect several hours of dedicated runs for a full level-51 prism with four fusions.

What is the best Prism build?

There isn't one universal answer — build the four fusions and legendary around your archetype combo. Survivability picks (Unbreakable, Steel Plating) dominate tank builds; Unbridled or Wrecking Ball define damage builds.
