What Is Calyx
A Quest That Offers Various Upgrade Materials Upon Completion

Calyx is a flower-shaped challenge found in various locations. You can select the difficulty level, and by completing the quest, you can obtain materials to enhance your characters or Relics. Each Calyx can be challenged multiple times as long as you have enough Trailblaze Power.
Trailblaze Power Is Required

| Trailblaze Power | Required Stellar Jade | Times Limit |
| 60 | 50~150 | Up to 8 times per day |
▲ Trailblaze Power can be replenished by consuming Fuel or Stellar Jade. The amount of Stellar Jade needed gradually increases.
Calyx's challenge consumes 10 Trailblaze Power, which can be exchanged for Fuel and Stellar Jade, and is recovered every 6 minutes. Trailblaze Power is also needed to collect Relics and Ascension Materials, so plan accordingly.
Trailblaze Power is consumed not at the start of the challenge but at the time of receiving the reward, so you can attempt the challenge as many times as you need.
The Higher The Difficulty, The More Luxurious The Rewards

Calyx has different difficulty levels. As you raise the Equilibrium Level, you unlock higher difficulties. The drop rate per Trailblaze Power increases with difficulty, so consume Trailblaze Power early to raise your Trailblaze Level.
Up To 6 Times Can Be Done Automatically

If you have enough Trailblaze Power, Calyx can automatically battle up to six times. This feature lets you gather materials all at once, but it won't restore your HP or Energy between battles. Only use it if you have a suitable team with a Healer.
Available Difficulty For Each Trailblaze Level
*To raise the Equilibrium Level, you need to complete the Trials of the Equilibrium that are unlocked after reaching the Trailblaze Level.
| Trailblaze Level | Equilibrium Level | Difficulty To Unlock |
| Lv.0 ~ 20 | - | - |
| Lv.20 ~ 30 | Lv.1 | I |

| Lv.40 ~ 50 | Lv.3 | III |
| Lv.50 ~ 60 | Lv.4 | IV |
