After the overwhelming performances of certain characters in the first season of Galactic Disaster, a wave of buffs and nerfs have come to many characters in the game, with some having massive changes to their skill kits and some only getting minor number changes. 

Here are all the important buffs and nerfs for characters players need to know for the Chaos Zero Nightmare February Balance Patch:

Among the characters buffs and nerfs changes coming to the update patch, several major gameplay mechanics will experience changes:

MechanicChangesChange Effect
AgonyOverviewAgony Effect has received a change to make it easier for players to apply them and to limit its damage potential for game balancing.
Agony Mechanics– Is now treated as a single debuff instead of multiple instances of debuffs.- Multiple applications will increase the stacks instead of prolonging duration.- Deal more damage based on the amount of stacks.
Agony Continuous Effect– After triggering, halves the current stack’s amount of Agony instead of reducing the stack by 1.
CounterattackOverviewCounterattacking has received an overall buff in its effect, allowing it to deal more damage overall to facilitate the counterattack playstyle.
Counterattack Stats– Increase Damage Dealt by Counterattacks.
Counterattack Mechanics– Counterattacks can now deal critical damage based on critical stats of the user.

Among the characters getting their skill kit buffed and nerfed during this update patch, 2 of them experience the most amount of changes, with their skill kits being entirely reworked. These characters are Tressa and Cassius.

Tressa
OverviewTressa’s performance during the 1st season of Galactic disaster was too overwhelming, with her gameplay mechanics threatening the overall balance of the game, therefore, she has experienced a massive change in playstyle.
The philosophy behind her playstyle changes is to limit the amount of daggers she can create with healing and instead increase the damage output of her individual shadow dagger cards damage output instead. Additionally, she will now be able to create advanced shadow daggers at 0 cost and alternate between using normal shadow daggers and advanced shadow daggers to deal damage to enemies.
Shadow Dagger & Advance Shadow Daggers– Shadow Daggers now deal more damage.- Advance Shadow Daggers now cost 0 and deal more damage based on Agony stacks.
Shadow Reload– Massive changes to Epiphany Effects: Remove create shadow daggers upon healing epiphany effect.- New Epiphanies that can create advanced shadow daggers.
Vital Attack– Reduce cost and now apply more Agony stacks on enemies.
Cursed Gouge– Now immediately activates the Agony effect on enemies.

Overall, these changes completely shut down Tressa’s infinite dagger creation effect and makes her deal less Agony damage to enemies overall. However, it opens up a brand new playstyle for Tressa and still helps her remain a top DPS character in the game.

Cassius
OverviewCassius doesn’t get much of a change compared to Cassius, with only changes to his ability to heal and apply Morale Reduction to enemies, helping him to sustain the team better.
Crucially, his most important card epiphany has been nerfed with it having the unique tag, making it impossible for players to create multiple quest cards, so players should pay attention to this.
Overall Mechanic Change– Improve healing amounts.- Added Maximum cap on certain damage increase effects.
Dice Trick– Added Morale Reduction Effects on enemies when Quest is completed.- Epiphany 5 now has a Unique Tag.

Cassius’ changes doesn’t affect his playstyle too much but does massively reduce his own damage output potential, making it harder to use him overall.

Finally, for the February balance adjustment patch, a large number of characters will be receiving adjustments in their skill kit, effects and overall stats to help optimize their playstyle and more.

The first important adjustment is that Supporter class characters will receive changes to their healing effects, helping to boost their abilities to sustain the team better overall.
