First Time Reward: 1200 Libra
1-Star: 1 /1200 Libra
2-Star: 1300/ 3600 Libra
3-Star: 2500/ 6000 Libra
The best servan for the job is a Plumie and its explosive burst skill. Having an Arachne or Golem will allow you to attract all enemies as close together as possible so you can defeat them in one blow. There are several waves of golems and you'll have ample time to finish the challenge. However, to get a higher score, you have to defeat the golems as fast as possible.
Ultimate Power of Servans
Most of Arnice's strength will be sealed away so utilize your Servan's full potential to destroy this powerful boss.
First Time Reward: 120 Blood
1-Star: 1/360 Blood
2-Star: 2000/ 600 Blood
3-Star: 2800/ Mark of Symphaty x1
You only need to defeat the Gargoyle using only your servans. Basically, the more poweful Servans you bring, the quicker you can defeat the boss.
Trapped
Find and defeat all enemies hidden inside the treasure chests. Efficiently opening the chests will be the key to your success.
First Time Reward: 600 Libra
1-Star: 1 /1800 Libra
2-Star: 1500/ 3000 Libra
3-Star: 2250/ Gold Bar x1
You have to attack the chests to open them. Use large area-of-effect skills, like the Golem's taunt to open multiple chests at once. Defeat all the enemies that will spawn from the chests to complete the challenge. Complete this task at the shortest time possible to get the highest reward.
Beyond Obstacles
Breakable barriers are not the only obstacles. Sometimes, enemies will stand in your way too. Complete this by destroying all targets.
First Time Reward: 240 Blood
1-Star: 1/240 Blood
2-Star: 2000/ 720 Blood
3-Star: 3000/ 1200 Blood
Using servans capable of using wide-area attacks and hitting multiple enemies will excel in this task. Basically, you have to destroy all objects and defeat all enemies in order to complete the task. Wide-area attacks can destroy multiple objects and defeat several enemies at once.
Can't Catch Me!
Defeat fast-moving enemies by trying various methods to catch these speedsters.
First Time Reward: 1200 Libra
1-Star: 1 /1200 Libra
2-Star: 2000/ 3600 Libra
3-Star: 2500/ 6000 Libra
The Servan Arachne's burst skill, Hunter's Web will be your efficient tool in stopping these fast-moving enemies on their tracks. The web has a large coverage and will instantly stop any enemy stepping on it. The enemies won't get taunted by the golem so you can carry at least two arachne if you can afford them and two attackers like the wolf or toy sentinel which can use very fast offensive burst skills.
HP for Days
The enemy possess an enormous amount of HP. Much training will be needed in order to defeat it within the time limit.
First Time Reward: Mark of Fitness x1
1-Star: 1/120 Blood
2-Star: 4000/ 360 Blood
3-Star: 4500/ 600 Blood
First, take out the healers and concentrate in attacking the boss. The higher Arnice's level as well as her servans, and the better their gears, the faster they can whittle down the boss's enormous HP. Bringing an all-attacker servan team can also increase your damage output significantly.
10 Chain
Attack targets to connect a 10 chain. The Gladiator equipment is recommended
First Time Reward: 1200 Libra
1-Star: 1 /1200 Libra
2-Star: 2000/ 3600 Libra
3-Star: 2750/ 6000 Libra
You have a full party of Dinoswords for this task. The enemies are volatile bombs so having the Gladiator equipment on Arnice will give you a 5-second leeway to chain your kills. At the start of the task, summon all your servans and start attacking the targets.
