Illuvium: Arena Update 1.18.3
Patch Notes
- Date PublishedSep 16, 2026


Overview
This update introduces the Event Pass! This feature and the accompanying tournament will be handled in a separate blog post in-depth. Acting like a mini Battle Pass. Play and complete quests to earn Arena Points each Event to earn Illuvials, XP Boosts, Fuel and some cosmetics. This update includes a swath of changes to make balancing easier in the future while also emphasizing the Hyper system more as standout for our game. It also includes redesigns to synergies and removes Composite chips while changing max Composite stacks to 3 across the board.
Synergies
Hyper: Scaling Hyper is class-flavored now, and the cap is lower. At full hyper Damage Amp and Damage Reduction is still 10%.
- Fighter: Attack Speed, 0.3% per point (max 30%)
- Bulwark: Max Health, 0.3% per point (max 30%)
- Empath / Psion: Omega Power, 0.3% per point (max 30%)
- Rogue: Crit Chance, 0.3% per point (max 30%)
Hyper also charges slower within the same Affinity matchup, emphasizing the difference between getting Hyper and not getting Hyper. The design goal is for a mono matchup to be a clear victory for the Affinity with a Hyper advantage, unless the player with the disadvantaged Affinity has an immense TPI and Level advantage
Air: No longer gives Dodge. Your team gains Energy Resist instead (Air units still get double). At max Air, getting hit fires Energy Damage based on Omega Power.
- Team Energy Resist: 10 / 20 / 30 (Air: 20 / 40 / 60)
- Max Air zap: 10% of Omega Power as Energy Damage
Earth: No longer gives Mitigation. Your team gains Physical Resist instead (Earth units still get double). At max Earth, Earth units get Mitigation.
- Team Physical Resist: 10 / 20 / 30 (Earth: 20 / 40 / 60)
- Max Earth Mitigation: 50
- Thresholds are now 2 / 4 / 6
Bulwark: No longer gives Resistances. Your team gains Max Health instead (Bulwark units still get double). At max Bulwark, they grow Thorns from their Health.
- Team Max Health: 5 / 10 / 15% (Bulwark: 10 / 20 / 30%)
- Max Bulwark Thorns: 1% of Max Health
Empath / Fighter / Psion / Rogue: Same kits, less of the team stat, Hyper is doing more of that job now.
- Empath Shield: 5 / 9 / 14% → 3 / 6 / 10%
- Fighter Attack Speed: 5 / 7 / 10 / 16% → 4 / 6 / 8 / 10%
- Psion Omega Power: 8 / 16 → 5 / 10
