RNG Heroes BOSSES Update: Bosses, Artifacts, and Crates

The BOSSES update is the live combat depth patch in RNG Heroes. It added boss-tier enemies with artifact drops inside each biome, and is the patch context for the current BossUpdate and Batteries codes. The developer has not published a boss drop-rate table or a full artifact list, so this page keeps the verified Abyss Reaver Crate as the only named artifact and treats every other drop-table claim as rumor.

What the BOSSES update added

The AllThingsHow progress guide, the Earnaldo codes guide, and the NoobBlox beginner walkthrough describe the BOSSES update as adding:

• Boss-tier enemies that spawn inside each biome after a kill threshold.
• Artifact drops in the form of equippable crates that grant permanent stat bonuses to a slotted hero.
• The Abyss Reaver Crate as the only named crate surfaced by an active code.

The official description confirms the headline mechanic (“fight epic BOSSES and collect their artifacts”) but does not publish any specific artifact, drop rate, or boss HP value.

The verified artifact: Abyss Reaver Crate

The BossUpdate code grants 1 Abyss Reaver Crate per the PCGamesN codes tracker, Eurogamer’s tracker, TryHardGuides’ tracker, the AllThingsHow codes page, and the MobileMatters codes page. The crate equips to a hero for a permanent stat bonus in the same way a named equip crate would in any Roblox auto-battler. The exact stat magnitudes are not published.

This is the only artifact this wiki treats as verified. The BOSSES update may drop other crates inside biomes, but the developer has not published a list of them, and the community guides do not converge on additional names.

How bosses fit the existing loop

The BOSSES update does not change the core loop, the upgrade tree, or the Prestige thresholds. The change is local to combat depth:

1. Biomes still gate progression. Dark Forest still costs 6,000 Gold and The Beach still costs 100,000 Gold.
2. Kills still drop Gold and XP. The Loot branch and the Luck upgrade still drive the income rate.
3. Bosses add a per-biome payout. Inside each biome, after a kill threshold, a boss-tier enemy spawns with a crate drop on defeat.
4. Crates equip to heroes for permanent bonuses. This is the only verified artifact in the live build.
5. Prestige still resets at Level 10. The reset still returns level and Gold to zero and grants Prestige Points for permanent multipliers; the BOSSES update is a within-run progression, not a between-run mechanic.

The recommended order stays: buy the Upgrade & Luck Scenario tool buy queue, push to Dark Forest, then The Beach, then run the boss spawn inside each biome for the artifact payout.

How the BOSSES update changed the codes roster

The BOSSES update is the patch context for two of the five currently active codes:

Redeem BossUpdate once the BOSSES update is visible on your server. The crate will be delivered through the standard reward popup. See the codes status page for the full redemption flow.

What this page does not publish

• The complete current boss roster. The community descriptions mention a “Mystery Boss” tied to the description’s ??? icon, but no source we cite has published a list of named bosses.
• Drop rates for any boss. The Earnaldo gamepass guide explicitly disclaims any published drop-rate table.
• Drop rates for the Abyss Reaver Crate beyond “1 per active BossUpdate code redemption.”
• Per-hero stat magnitudes for any crate. The crate equips and grants bonuses; the magnitudes are unverified.
• Boss HP and reward multipliers per biome. The developer has not published these and the community guides stop at the entrance cost.

The codes status page is the source of truth for the active code list and the Prestige & Zone ROI Scenario tool is the way to plan the Gold cycle around the boss unlocks.
