Lit Up Braziers To See
Since the quest area is in an underground ruin, you will have to light up the braziers as you go in order to see the way.
Use Guila for Brazier Lighting
Guila is a good character to use for her Exploration Skill that can aim and immediately light up braziers. Other Fire characters can be used as well, and it's better if they have a fast attack speed.
Obstacle Course Tips
The above characters can help make the obstacle course much easier to do and have more time for errors. Guila can allow you to hit the Fire Stone from afar to activate the Brazier.
Use Tioreh or King's Exploration Ability To Skip a Section
Tioreh and King’s abilities can be used to skip the moving block section that pushes you off the platform. Head to the slide and use their skill to reach the other end safely.
Act 10 Bosses Guide
Avoid Using Ultimates at the Wrong Time
▲ Video showing the boss change to Decoy immediately once he takes Ultimate damage.
The second boss can unleash a powerful attack when its Decoy is active. The Decoy is summoned whenever an Ultimate is used while the boss is not Dazed. Move far away from the Decoy to avoid the attack.
Unique Daze Meter
Unlike the other enemies, the boss for Act 10 cannot be Dazed using attacks. He instead has a Daze counter that appears periodically and fills up by 1 each second. It will take eight (8) seconds before the boss is Dazed once it shows up.
Use Ultimates When Dazed
The only time that is good to use Ultimates is when the boss is Dazed. This is because the doll summoned after the Ultimate will take any further damage first before the boss reappears.
Use Tag Attacks On The Third Boss
The third boss for Act 10 can use multiple dash attacks consecutively. Tag Attacks can stop it from using those attacks, as well as Daze the boss.
