After clearing Season 1 stage 9-5 : The Responsibility of the Guilty, you will unlock the Quirk system.
Quirks are a permanent, account-wide enhancement system available in the Base → Quirk menu. They provide additional stats for your heroes or utility effects for your account, and are unlocked using materials such as , , and .
Category Overview
Counteract Strong Enemies: bonuses that enhance your team or weaken the enemy when facing bosses
Class Enhancement: stat boosts for heroes based on their class and subclass
Element Enhancement: stat boosts based on hero elements
Utility: account-wide bonuses (EXP gain, drop rate, crafting cost, etc.)
Adventure License: bonuses that only apply in Adventure License mode
How It Works
- Each category has Main Nodes and Sub-Nodes. You must upgrade the main node to unlock its sub-nodes.
- You need 5 points in a main node to unlock all sub-nodes (except Adventure License, which requires level 9).
- Some nodes are more valuable than others. You can skip early nodes like
Healer, 
Defender, 
Ranger (
Tactician), 
Damage Reduction and 
Resilience quirks. - You can reset quirk investments using , refunding all materials spent.
Upgrading Priority
In the early game, your first priority should be Counteract Strong Enemies quirks, as their bonuses apply universally — regardless of enemy, game mode, hero class, or element.
Next, focus on Class Enhancement, starting with the class of your main DPS. Then move on to Element Enhancement, prioritizing the element your team relies on the most.
Finally, consider Utility quirks, which offer account-wide bonuses such as EXP gain, drop rate, crafting discounts — and most notably, an increase to your stamina cap. While the stamina cap boost is the most impactful perk in this category, Utility quirks as a whole still remain a lower priority early on.
As for the Adventure License tree: this is an endgame system and shouldn't be your early focus. It's also the only tree that requires , which is exclusively obtained from Adventure License mode.
Early Game Example
Let's take a common early team: Valentine, Aer, Monad Eva, Drakhan.
- After unlocking boss quirks, prioritize the
Striker tree — especially the left path, which benefits Attackers like Aer and Drakhan. - Then, upgrade the
Fire tree (Valentine and Aer) — one of your early goals will be farming Chimera for Speed gear. - Then, invest in
Light quirks for Drakhan and Monad Eva.
This is just one example — always adapt your quirk investments based on your team composition and progression goals.
