Season 3 [Temporal Vortex Difficulty IV] Leaderboard Rush Guide

Temporal Vortex is a mandatory daily challenge, where you can obtain the Echo of Clepsydra as ranking rewards. These rewards will significantly impact the Traveler's seasonal ranking.
This article will briefly introduce the rewards and rules of Temporal Vortex, listing seven team compositions that have performed exceptionally well in Season 3. These teams can far exceed the scores needed for the highest tier of rewards even on auto-combat. This guide will help Travelers choose the right team based on their heroes' development and the current battle rules to aim for higher leaderboard positions.

[Rule Description]
When you are able to deal over 15M DMG in Temporal Vortex at Difficulty III in a single hit and are above Journey Level 35, you can take on the challenge at Difficulty IV.
The rewards for a phase will be calculated using the total damage your team deals to the Sea Deity within 20 minutes of this challenge. Players will also be ranked based on the damage they can deal in a single hit, and the ranking rewards will be distributed on the next day.
Difficulty IV offers three tiers of rewards. When you deal more than 25M damage in a single hit, you can claim the highest tier of reward. Here are more details:
 
The ranking rewards are as follows:

[Battle Rules]
Difficulty 4 features periodically changing rules. Players can choose their DPS based on specific Damage Bonus the boss will take. For example, if the current challenge states that the boss will take extra Derivative Damage, then Poison and Wild comps will have a significant advantage. The damage numbers shown in the recommended lineups is produced under these rules, and some teams can achieve even higher damage under more favorable rules.

●Considerations for a Suitable Lineup
The Corrosion Comps are arguably the strongest in this season's Temporal Vortex. As long as you have all the team members, they have the capability to compete for top spots on the leaderboard under any rule.
Especially under the rules where the boss receives increased Poison Damage and receives increased Crit Damage, the Corrosion Comps become even more powerful.
 
Lineup: Frurbath + Oggok + Rook + Whisk + Dargo
Positioning Example:

●Team Aura
For this team, we will select Rook's Attack Aura to boost damage.
●Skill Timing Example
Note: The boss releases a skill every 5 seconds, with a 20-second cycle. The first skill has a longer pre-casting action. Oggok, releasing his ultimate skill as shown, can take care of the first three skills of the boss with the Immortality effect provided by his ultimate skill. He can then immediately trigger healing and dispel the Defense Penalty inflicted on your team by the boss after the third skill is released.

●Explanation for Hero Substitutes
In this lineup, if Whisk is not available, Sacredeia can be used as a replacement. In that case, Sacredeia's recommended Artifacts are Swamp Toadstool or Dawn Pipe Organ;
If the current rule enhances your team's Shield strength, Oggok can be replaced with Felosia.
● Important Notes
Since Whisk's ultimate skill deals multiple instances of damage, it can easily trigger the artifact effects of Witch's Remains or Crown of the Unclean, which applies Defense Penalty on the boss. Therefore, it is recommended to stack Accuracy on her and choose the aforementioned Artifacts to increase team damage. If Sacredeia is used instead of Whisk, Witch's Remains should be quipped by Dargo;

[Other Suggestions]
1. Before the Elemental Affinity level of the five heroes is maximized, ensure that your deployed heroes can activate the three-hero Elemental Affinity buff. As for tanks, prioritize Zeffi and Oggok, who can take turns using their ultimate skill to provide Immortality and Invincibility, ensuring the team's survival even when the boss has over 150 stacks of the all-stat bonus.
Especially for the team with Elemental Affinity of Lightning and Necrosis from this season, support heroes and defensive heroes will find it more difficult to protect allies, and DPS heroes will struggle to survive. By switching tanks, you can significantly better enable the DPS.
2.The Corrosion Comps added in Season 3 is very powerful under various rules. As long as you have the core DPS—Rook, even with just the Epic hero combination of Dargo and Gegnu, you can achieve a damage performance comparable to that of to other Comps' full lineup;
3. Your actual damage output can fluctuate during the challenge. If you want to climb up the leaderboard, you can replay the challenge multiple times and only save that day’s damage record when you are satisfied with the result.
