Defeat the Mountaintaur

| Time Limit | 5 Minutes |
| Recommended Level | 21 |
| Recommended Element | Electric |
The Mountaintaur is a melee-attacker with a handful of charge and leap attacks. You can stay right next to it to attack, but be ready to dodge at any time for its club swings. When it does its successive charged attacks, focus on dodging until it stops.
Defeat the Rock Fist Dude

| Time Limit | 5 Minutes |
| Recommended Level | 27 |
| Recommended Element | Wind |
The gems on the back of the Rock Fist Dude is its weakness, so try to target it as much as you can. It mostly uses melee attacks, but it does have an attack where it rains down Earth damage. You can dodge this by looking at markers on the ground.
Defeat Void Flora

| Time Limit | 5 Minutes |
| Recommended Level | 30 |
| Recommended Element | Fire |
During the fight with Void Flora, you'll also have to deal with Orcs while waiting for it to expose itself. It becomes vulnerable to damage whenever it readies a powerful attack. Deal as much damage as you can during this window to lower its health and interrupt the attack.
Complete The Required Side Quests

When you reach this part of the quest, take it as a chance to strengthen and enhance your characters. Increase their skill levels and use Conquest materials to craft gear. This is highly recommended, as the final boss of the episode is quite strong.
Defeat Amon

| Time Limit | 5 Minutes |
| Recommended Level | 30 |
| Recommended Element | Wind |
Amon is the final boss of this episode and is the hardest challenge you have faced so far. He has both short- and long-range attacks and can deal a large amount of damage. If you are unprepared, you may not be able to beat him within the time limit.
Stuck in Episode 2? Tips and Fixes
Level Up and Perform Breakthroughs

Boss battles have a "Recommended Level." As a general guideline, you should level up all team members so they are at least equal to the boss’ level.
Farm EXP Materials in "Experience Training"

If you're low on EXP materials, run "Experience Training" in the EXP Paths. After the first clear, you can use the skip feature to farm it repeatedly.
Paths Reward and How to Unlock
Craft and Enhance Set Equipment

Set Equipment refers to 4★ or higher gear crafted using boss and ore materials. In the early game, prioritize crafting a variety of equipment rather than focusing on Set Effects.
How to Craft Equipment and Optimize Stats
Enhance Equipment to at Least Level 3

Enhancing equipment to levels 3 and 9 grants additional stat bonuses. After obtaining your gear, prioritize raising all equipment to at least level 3 first.
Change the Difficulty to "Path of Dawn"

If you want to enjoy the story without getting stuck on boss fights, lowering the difficulty is a recommended option. You can select "Path of Dawn" in the Controls section under Settings to reduce enemy attack power and durability.
