This update delivers a balance patch and a bug fix affecting Leviathan stats.

Gameplay & System Updates

Bug Fixing

  • Fixed an issue that caused TPI stats from Illuvials to only scale up to 25% instead of the intended 40% on the max threshold.

Balance Adjustments

This update focuses on reducing the dominance of standout synergies such as Aegis and Mystic, while toning down overperforming lines like Elk (Ador / Adoredo / Adorius) and Beetle (Titanor). At the same time, it brings underperforming archetypes like Tsunami and Shock closer to viability, and restores some power to Rogues and Vanguard, which were hit hard in the previous patch and needed a slight boost to become competitive again.

Illuvials

Thylacine (Dash/Rake/Umbre): 
Helping Stage 2 and 3 version of this line a bit.

  • Attack damage: 105/145/185→ 105/150/195.
  • Health: 1450/1900/2500 → 1450/2000/2700.

Elk (Ador/Adoredo/Adorius): 
Its omega's impact is too powerful.

  • Energy cost: 200→ 220.

Beetle (Scarabok/Goliant/Titanor): 
Stage 3 Omega deals too much damage for a tank.

  • Omega Damage: 275/350/525→ 275/350/475.
  • Health: 1850/2400/3450 → 1850/2400/3500.

Affinities & Classes

Rogue: 

Higher threshold rogues need a small tune up since last patch.

  • Crit Chance: 6/12/18% → 6/13/20%.

Nature: 

Nature 4 reward to accessibility ratio is too high in Leviathan.

  • Health Regeneration: 1/1.75/3/3.5% → 1/1.5/3/3.5%.

Empath: 

High threshold empaths are benefiting a lot from bigger Health pools in Leviathan.

  • Max Health Shield: 5/10/15% → 5/9/14%.

Composites

Spore:

 Spore performance is below expected considering its achievement effort.

  • Healing on omega: 9/12/15% → 10/13/16%.
  • Energy burn on omega: 9/12/15% → 10/13/16%.

Shock:

 Shock has been one of the worst performing synergies of the latest patch.

  • Lightning Damage: 330/385/440% → 350/400/450%.

Invoker:

Invokers are a strong synergy, but not strong enough compared to its achieveiment difficulty.

  • Omega Power gain based on energy cost:  10/14/16% →11/15/17%.

Tsunami: 

Like Shock, has been one of the worst performing synergies of the latest patch.

  • Energy Refund: 28/32/36% → 30/35/40%.
  • Damage based on Energy Cost: 280/320/360% → 300/350/400%.

Vanguard:

Vanguards got hammered last patch. Helping them a bit to become competitive again.

  • Max Health Bonus Damage: 2/3/5% → 3/4/6%.

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%.

Mystic:

Mystic has been dominating in this patch, tuning it down accordingly.

  • Damage AMP and RED:  8/18/30% →7/15/25%.

Harbinger: 

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

  • Omega Power gain: 80/120/160→ 70/110/150.
