[World Boss: Contagion] offers a Practice Mode within Normal and Challenge Modes.
- Consumables, Life Tokens, and durability are not consumed in Practice Mode.
- Daily rewards are not earned in Practice Mode, and your results are not reflected in the rankings.
Offset
In the [World Boss: Contagion] content, you can use the Offset skill with Dungeon Special Key 1.
Pressing the Special Key charges Offset, and releasing the key activates it immediately.
If you face a monster and land the hit against its particular attack, the monster will temporarily be neutralized and the damage received by the monster will increase cumulatively based on the charge tier.
The constant damage increases based on the Offset charge tier are as follows.
|

|
Tier 2 |

Tier 3 |

If the Offset is successful, you can immediately reuse the Offset skill.
