What’s Inside Eternal Return Patch 9.4
The November 27 update introduces sweeping changes to hero kits and weapon mechanics. Character and weapon mastery XP curves receive adjustments that delay mid-game power spikes while accelerating late-game progression to mastery level 20. This prevents excessive grinding at higher tiers while maintaining balanced early-game pacing.
Camera shortcuts now target Mythic Air Supply Boxes instead of Legendary Boxes, and cycling through Meteorites displays all active meteor locations sequentially. Main stats display updates offer clearer in-game information for offensive and defensive metrics, helping players make faster decisions during intense fights.
Hero Balance Changes and Stat Adjustments
Multiple heroes receive base stat buffs to offset False Oath mechanic changes. Debi & Marlene gain increased HP per level (85 → 88) and defense per level (2.8 → 3), while Hisui sees HP per level climb from 94 to 96 and defense per level rise from 3.5 to 3.7. Abigail’s base HP jumps from 950 to 970 for better early survivability.
Li Dailin faces nerfs targeting her P – Blood Alcohol Content (BAC) passive, while Laura and other overperforming characters receive damage reductions on key abilities. Aya gets cooldown reductions and damage adjustments across all weapon types to address her weak performance. Aiden’s P – Overcharge and linked skills become smoother and more rewarding, compensating for False Oath changes that affected his kit.
Inspiration (W) undergoes a complete damage accumulation formula rework, scaling differently and incorporating extra attack power. Several movement and control skills gain or lose cooldown time and crowd-control duration based on performance data.
Weapon and Item System Overhaul
Scythe loses its unique attack range passive and gains a new Healing Reduction – Weak passive that cuts enemy healing by 40% for four seconds on hit. The Golden Ghost sees skill amplification drop from 85 to 82 and cooldown reduction decrease from 15 to 10, paired with a fresh unique passive.
Cameras, tonfas, throws, bows, and other weapon categories receive minor adjustments to attack power, attack speed, life steal, or movement speed. A new Biotic Infusion unique passive appears on select items, granting attack speed and bonus on-hit skill damage after casting abilities. Older weak healing-reduction passives disappear from those item slots.
Tactical skills including Prayer, Meteor, Nullification, Impulse, and Mythic undergo cooldown increases and shield or damage scaling reductions. Mythic cooldown extends from 30 seconds to 40 seconds, while Nullification cooldown grows from 20 seconds to 25 seconds. These changes reduce extreme swing potential in late fights and shift power back toward hero execution and smart itemization.
Fatal Ultimatum and Plasma Nova receive damage number and ratio reductions to prevent single items from deciding matches.
New Season 9 Content and Rewards
Patch 9.4 adds new Leon emotes alongside a Season 9 team bundle collection featuring team profile backgrounds, borders, team slot backgrounds, and team emotes. Players who obtain all items within specific bundles unlock collection rewards including three-day XP boosts, A-Coin bonuses, and ER Point accelerators.
Updated item probability tables activate for Skin Data Box, Research Center Data Box, and cosmetic-focused containers plus random skin vouchers. Disassembly outputs receive tuning for designs and completed items affecting team slot backgrounds, character cosmetics, rare skins, emotes, BGM, and drones. Official documentation lists exact percentages for each box category and disassembly option, allowing players to verify odds when chasing specific cosmetic drops.
