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

Gameplay & System Updates

Bug Fixing

  • Fixed an issue in Leviathan mode where Illuvials were generating more energy from damage taken than intended. Illuvials now correctly gain 1 energy per 40 damage taken (previously, they were earning roughly double this amount). This fix should reduce excessive ability usage from units like Titanor and prevent unintended behavior such as Rhamphire’s “infernal trampoline"..
  • Fixed an issue where certain cosmetic assets, including Drone Skin (GShock) and Battleboard Skin (Wave 5), were not displaying properly.

Balance Adjustments

This update focuses on addressing the dominance of specific synergies like Frost, Harbinger and Mud. And tunes down some well performing lines like Elk (Ador / Adoredo / Adorius), Penguin (SlaSlashin) and Mammoth (Mah'mu / Mah'th / Mah'mut).

Illuvials

Tiktaalik (Ebb/Fludd/Geyyser): 
Helping Stage 2 and 3 version of this line a bit, its omega was too weak.

  • Omega damage: 75/125/175 → 75/135/200.
  • Omega healing: 75/125/175 → 75/135/200.

Elk (Ador/Adoredo/Adorius): 
Nerfing Stage 2 and 3 versions of this line, its omega was too powerful.

  • Omega % missing health damage: 15/20/30%→ 15/18/25%.
  • Omega % missing health healing: 15/20/30%→ 15/18/25%.

Penguin (Slappin/Stabbin/Slashin): 
Nerfing Stage 2 and 3 versions of this line, its exponential scaling is too rewardingl.

  • Attack Damage: 100/150/200%→ 100/140/180.
  • Omega Energy Attack Damage gain: 70/90/130→ 70/85/100.

StarnoseMole (Lura/Loulura/Malura): 
Reducing the capacity to taunt quickly on combat start.

  • Starting energy: 60 40.

Mamooth (Mah`mu/Mah`tu/Mah`mut): 
Its omega is too big of a powerhouse. Reducing its casting frequency.

  • Enercy cost: 200 220.

Affinities & Classes

Fire: 

Fire is clearly underforming in the current meta, helping it.

  • Bonus Attack Damage: 5/12/20% → 6/13/23%.

Fighter: 

Fighter 5 has been still overperforming despite last nerf. Tuning it down a bit further.

  • Bonus Attack Speed: 6/9/13/18% → 6/9/12/18%.

Composites

Spore:

 Spore performance is below expected considering its achievement effort.

  • Healing on omega: 8/11/14% → 9/12/15%.
  • Energy burn on omega: 8/11/14% → 9/12/15%.

Shock:

 Shock has been the worst performing synergy of the latest patch.

  • Lightning Damage: 300/350/400% → 330/385/440%.

Frost: 

Frost dominates even after nerfs on Jotun and Behemoth.

  • Shield gained: 500/800/1200 → 400/700/1100.

Harbinger: 

The amount of omega power given by harbinger is making its units shing too bright.:

  • Omega Power gain: 80/135/180→ 80/120/160.

Mud:

 Slightly overperforming given its achievement difficulty.

  • Attack Damage and Omega Power steal: 26/34/42% → 24/32/40%.

Aegis:

Another composite whose effort to reward ratio was too high in this patch.

  • Shared Attack Damage, Attack Speed and Resistances:  10/11/12% →9/10/11%.

Invoker:

Early thresholds of Invoker made pistolshrimp scale Omega Power way too fast. This also spiked since last patch water buff. Adjusting it accordingly.

  • Omega Power based on energy cost:  12/15/16% →10/14/16%.

Magma: 

Magma 2 was doing well even though fire was underperforming. With fire buff, we anticipate magma 2 to do even better, for this we are preventively nerfing it a bit:

  • Mitigation gained: 7/8/10→ 6/8/10.

Forge Augments

Restorating Impact Reactor: 

This Augment stacked up combined with Hyper Carries still outperforms other augmentation options.

  • Max Health heal on Takedown: 5→ 4%.
  • Resistance gain on Takedown: 7→ 5.

Arcane Omega Reactor: 

This Caster augment gave psion carries the capacity to heal too quickly from threats.

  • Omnivamp: 5→ 2%.

As always, we’ll continue monitoring gameplay, collecting feedback, and making improvements where needed. Jump in, test out the changes, and let us know what you think.

See you on the battlefield.
