Illuvium: Arena Update 1.8.1
Patch Notes
- Date PublishedMar 24, 2025

This balance patch introduces Augment and Illuvial balance changes, along with an additional 10 seconds per round to improve player decision-making and execution.
We've also implemented Leviathan Mode Multiplayer Support, enhanced matchmaking, and made several stability improvements for a smoother gameplay experience.
Additionally, we’ve fixed the Drone Damage system, addressing two major issues:
- Pets and Rangers were incorrectly contributing to Drone Damage.
- Damage modifiers were always applied one stage ahead.
- Example: When the modifier should have been -2, it was actually 0.
- When it should have been +3, it was +5 instead.
With this fix, damage scaling should now feel smoother and more controlled throughout gameplay.
