This update delivers bug fixes, a balance patch and the temporary removal of Ascendant mode.

Gameplay & System Updates

Ascendant Mode - Temporary Disable

Ascendant mode will be disabled from main menu until we can dedicate more resources to it.

Bug Fixing

  • Resolved an issue where certain Illuvials displayed incorrect icons on the XP screen.
  • Resolved an issue that caused a black background to appear when a new round loaded.
  • Resolved an issue where the Ranger level calculation was slightly lower than the correct value.

Balance Adjustments

This update addresses the dominance of Air, Fighter and Behemoth compositions while improving underperforming Water-based synergies. Additionally, several augments have been rebalanced to provide percentage-based scaling instead of flat increases, and energy gain from damage taken has been adjusted to better align with Leviathan’s larger health pools.

Game Rules

Energy Conversion on Damage Taken: 
With Leviathan’s increased effective health pools, units were generating energy too efficiently from damage taken, causing energy bars to fill excessively fast and disrupting overall balance. To address this, the damage-to-energy conversion rate has been reduced.

  • Energy conversion on damage taken: Reduced by33%.

Illuvials

Thylacine (Dash/Rake/Umbre): 
Untargetability removal left Thylacine in a tough spot. We are buffing its omega to help him out.

  • Omega dodge duration: 1/1.5/2 → 1.5/2/2.5seconds.
  • Omega damage: 175/325/600 → 200/350/625seconds.

Affinities & Classes

Fighter: 

Fighter has been dominating in the meta, so we're tuning it down.

  • Bonus Attack Speed: 7/11/16/21% → 6/9/13/18%.

Nature:

Threshold 8 is slightly overperforming.

  • Max threshold missing health % damage: 1.5% → 1.25%.

Air:

Air synergy and composites are thriving, we are tuning the down a bit.

  • Dodge chance: 6/12/18% → 6/11/16%

Rogue: 

Rogues are slightly underperforming across the board, especially threshold 7.

  • Critical Chance: 7/14/22% → 7/15/24%.

Water: 

Water synergy is performing poorly in the current meta, specially in higher thresholds..

  • Energy regeneration: 1.2/2.4/3.8/5% → 1.2/2.6/4.2/6%.

Earth: 

Leaviathan heavy hits has left mitigation slightly underpowered.

  • Mitigation: 4/10/15/20% → 4/11/16/22.

Composites

Behemoth: 

Despite being a high risk - high reward composite, Behemoth is too strong.

  • Max Health Damage: 10/14/18% → 8/10/14%.

Frost: 

Frost Damage AMP was helping too much Slashin and Jotun.

  • Damage AMP: 15/20/30% → 12/16/25%.

Tempest: 

The Omega Power gained on dodge is letting Tempest units scale to well.

  • Omega Power on Dodge: 3/4/6 → 2/3/5.

Bloom: 

Bloom is overperforming taking into account its accessibility:

  • Omega Power gain: 12/15/20→ 10/14/18.

Tsunami:

 Tsunami and Steam are severely underperforming.

  • Energy Cost Refund on omega: 22/26/32% → 28/32/36%.
  • Area of Effect Damage: 220/260/320 → 280/320/360.

Steam:

  • Damage AMP: 8/11/14% → 10/13/16%.
  • Energy Regeneration: 8/11/14% → 10/13/16.

Colossus:

Early thresholds of colossus were not compensating enough the effort put in:

  • Max Health Bonus: 16/28/40% → 18/30/40%.

Granite:

Granite composite was struggling at higher thresholds:

  • Invulnerable duration: 4/4.5/5 → 4/5/6seconds.

Mystic:

Mystic higher thresholds are very difficult to achieve, helping them a bit to feel rewarding:

  • Damage AMP and Reduction: 8/15/25 → 8/18/30%.

Forge Augments

Restorating Impact Reactor: 

This Augment stacked up combined with Hyper Carries like Jotun or Slashin created an invincible powerhouse.

  • Max Health heal on Takedown: 7→ 5%.

Safeguard Void Reactor: 

We are making the scaling for the below items percentual rather than flat.

  • Shield: 200→ 8% Max Health.

Immunis Void Reactor: 

  • Shield: 100→ 4% Max Health.

Stasis Cell: 

  • Health: 100→ 3% Max Health.
