Tower of Trials Overview
Tower of Trials Overview List
More Difficult Version of Infinite Tower
Once you clear the 100th floor of the Infinite Tower, you’ll unlock the Tower of Trials, where you’ll face stronger opponents—primarily Rare and Legendary characters.
Infinite Tower Guide4 Week Season System
The Tower of Trials features a weekly season system, where all cleared stage data resets at the end of each season.
Select Buffs or Debuffs
During Team Setup, you can add buffs to your party or debuffs to enemies for easier, faster clears. Alternatively, you can buff enemies or debuff your own party to make the Tower of Trials more challenging.
Rewards Earned Changes Depending on the Set Buff/Debuff
Before battle, you can apply buffs or debuffs. Strengthening your team or weakening enemies may lower the Achievement Medals you earn, while weakening your team or empowering enemies will increase them—so plan carefully!
Odd Number Floors Have Same Buffs/Debuffs
| Buffs/Debuffs List For Each Odd-Numbered Floors | |
|---|---|
| [Buffs] | 1. [Enemies] Inflicts DEF Reduction (always active) - [Enemies] Weakens monsters - Decreases DEF by 54% 2. [Allies] Grants ATK Boost (always active) - [Enemies] Weakens monsters - Increases All ATK by 38% |
| [Debuffs] | 1. [Allies] Inflicts Petrify for 2 turns - [Enemies] Strengthen monsters 2. [Enemies] Grants Death/HP Alteraton/Cooldown Increase Immunity. (always active) - [Enemies] Strengthen monsters 3. [Enemies] Nullify all DMG (3 times) - [Enemies] Strengthen monsters |
Odd-numbered floors (Floor 1, Floor 3, Floor 5, Floor 7, Floor 9...) usually share the same buffs and debuffs, serving mainly as a test of your team’s damage output. In contrast, even-numbered floors (Floor 2, Floor 4, Floor 6, Floor 8, Floor 10...) often introduce unique buff or debuff gimmicks to challenge your strategy.
Cannot Check Buffs/Debuffs For Locked Floors
Since you can only check the buffs/debuffs in the Team Setup, you can only see the status in the current unlocked stage. You cannot check out the buffs or debuffs from any locked stage.
You Can See Other Players' Clear Teams
There's also a Clear Info in the Team Setup panel where you can see all the stats and characters used by other players to clear the stage in Tower of Trials.
It's Also Possible to Copy the Team
As you check the Clear Teams, you can also copy their team to your advantage in clearing the stage.
