Best Paths for World 4

Destruction and Nihility

The best Path to take for World 4 is Destruction since it allows your team to deal increased damage at lower HP while also reducing the damage they take. The Path of Destruction works perfectly with Blade since his kit revolves around lowering his HP.

Nihility is also a Path that is great for World 4. Nihility offers extra damage with improved DoTs which are helpful if you have Guinaifen or Sampo in the team.

Get Preservation and Remembrance Blessings

Preservation has Blessings that improve shields for more survivability on top of boosting damage. If you're using Blade, we do not recommend picking up any Preservation Blessings since shields prevent him from losing health, hindering Blade from stacking his Talent!

Remembrance Blessings can freeze enemies giving you free rein to wail on them and is extremely powerful if you have Gepard as a shielder.

List of All Paths

Collect the Faith Bond and Seal Curios

Curio	Effect
Faith Bond	Reduces the Cosmic Fragments required for leveling up Blessings, resetting Blessings, and resetting downed characters by 30%.
Sealing Wax of The Hunt	Randomly gains 1 Blessing of The Hunt after obtaining this Curio. When choosing your Blessings after winning a battle, there is a greatly increased chance for Blessings of The Hunt to appear.
Sealing Wax of Nihility	Randomly gains 1 Blessing of Nihility after obtaining this Curio. When choosing your Blessings after winning a battle, there is a greatly increased chance for Blessings of Nihility to appear.

If possible, look for the Faith Bond Curio to upgrade your Blessings at a cheaper price or reroll for your Path Blessings. You can also collect the Sealing Wax Curios to further increase the chance of appearance for the Blessings of your chosen Path.

Best Characters for World 4

Character	Merits
Topaz	Most enemies in World 4 are weak to Fire, so Topaz is a top pick for a Fire DPS. She can easily apply Weakness Break to single targets, especially for Svarog.
Guinaifen	Since most enemies in World 4 are weak to Fire, Guinaifen can easily be slotted into a Burn DoT team. She can synergize with other Burn applicators as well, like Hook and Himeko.
Blade	Blade is perhaps the best DPS you can bring into World 4. He can easily apply Weakness Break with his Skill and Ultimate and he works with blessings from The Hunt or The Destruction. He has self-sustain and can thrive at low HP as well!
Huohuo	Huohuo is an amazing healer whose Ultimate regenerates the Energy of her allies while also buffing their ATK. With her Skill, she can heal and dispel debuffs from allies.
Dan Heng	Just like Blade, Dan Heng is an effective Weakness Breaker. He can easily free imprisoned allies, and he works well with the Crit stats from The Hunt blessings.
Black Swan	Black Swan is a DoT-based character that can stack Arcana DoTs on enemies. She is best paired with Kafka and her DoTs get stronger the more Arcana stacks an enemy has.
Sampo	Sampo is also an effective Weakness Breaker and deals decent damage with his DoTs. He can take advantage of the DoT augments from Nihility blessings.
Acheron	Acheron's main damage source is her Ultimate and you have to stack her Talent to use it. To do so, you need to inflict debuffs to enemies. With this, you have to surround her with Nihility characters and others who have a debuff in their kit.
Kafka	Kafka is a DoT damage dealer and she is great for World 4 since most enemies are weak to Lightning. She is best paired with DoT characters like Sampo.
Himeko	Most enemies in World 4, including Svarog, are weak to Fire and Himeko is the premier choice for Fire DPS. She can also easily deal with Svarog's summons.
Asta	Asta is the ideal Buffer for the Svarog fight. She can increase the Fire DMG of your Fire Main DPS, increase the SPD of all allies, and help shred Svarog's Toughness bar.
Gallagher	Gallagher is a healer who allows his allies to recover some HP as long as they attack an enemy affected with Besotted. He can also inflict an ATK reduction debuff using his Enhanced Basic ATK.
Hook	Hook is arguably a superior Fire DPS compared to Himeko, and can make better use of Nihility blessings with her Burn application.
Silver Wolf	Silver Wolf is a viable support for World 4 if you are running a team that mostly consists of Quantum characters. Also, you can add her to your team if you just need a Nihility character to apply various debuffs to enemies.

Best Teams for World 4

Free To Play Team

Main DPS	Support	Healer	Shielder
Dan Heng	Asta	Natasha	Trailblazer (Fire)
Paths & Blessings	Path: The Hunt Blessings: Hunt, Nihility, Preservation

For a full free-to-play team, Dan Heng, Trailblazer (Fire), and Asta will make short work of Svarog's Toughness bar as he is weak to Fire and Wind.

Optimal Teams

Follow-Up Attack Team

Main DPS	Sub-DPS	Support	Utility
Himeko	Topaz	Asta	Huohuo
Paths & Blessings	Path: Elation Blessings: Elation, Abundance, Hunt

This team comp has three Fire characters that can easily Weakness Break enemies with Fire weaknesses. Topaz can increase DMG from follow-up attacks, while Himeko will be the Main DPS, dealing AoE DMG. Asta supports the team with her ATK and SPD buffs.

With Huohuo on the team, Himeko and Topaz's DMG output will further increase due to the ATK buff that she gives after using her Ultimate. Also, she can provide some Energy to recharge their Ultimates.

If you don't have Huohuo, she can be substituted with a different healer such as Natasha, Bailu, or Luocha.

Blade Team

Main DPS	Support	Support	Healer
Blade	Bronya	Asta	Huohuo
Paths & Blessings	Path: Destruction Blessings: Destruction, Hunt, Propagation, Abundance

This team takes advantage of Svarog's and his arm summons' weaknesses to Wind. Imprisoned allies can be easily freed by Blade. Asta can boost Blade's ATK and SPD while Bronya allows you to give Blade a DMG buff and an extra turn using her Skill.

Like the previous team comp, Huohuo can be substituted with Natasha, Bailu, or Luocha!

Acheron Team

Main DPS	Sub-DPS	Support	Healer
Acheron	Jiaoqiu	Silver Wolf	Gallagher
Paths & Blessings	Path: Erudition or The Hunt Blessings: Erudition, The Hunt, Abundance, Nihility

With Acheron as the DPS, you want to surround her with a maximum of two Nihility characters to reach the full potential of the DMG buff from her Bonus Ability. So, Jiaoqiu and Silver Wolf can be added to the team.

Any character with a debuff in their kit will also work well with Acheron since every time they inflict it on an enemy, Acheron can stack her Talent which allows her to eventually use her Ultimate. With this, Gallagher is a solid choice for the team's healer.

Nihility DoT Team

Main DPS	Sub-DPS	Sub-DPS	Healer
Kafka	Black Swan	Guinaifen	Huohuo
Paths & Blessings	Path: Nihility Blessings: Nihility, Abundance, Preservation

This team requires Nihility as your Path. Kafka and Black Swan can dish out some high amounts of DoT while still being able to deal with Svarog's arm summons. Guinaifen can apply DoT as well and increase the DMG enemies take using the Firekiss debuff.

Like the previous team comp, Huohuo can be replaced by Natasha, Bailu, or Luocha. If you have a shielder like Gepard, pick up some Preservation and Remembrance Blessings as well.

Burn Team

Main DPS	Sub-DPS	Support	Healer
Hook	Guinaifen	Asta	Huohuo
Paths & Blessings	Path: The Hunt Blessings: Hunt, Nihility, Elation, Preservation

This team comp has three Fire characters to easily cut through Svarog's Toughness bar. Guinaifen can apply Burn and trigger it on demand using her Ultimate. Hook will be your Main DPS.

Similar to the previous team, Huohuo can be swapped out for Natasha, Bailu, or Luocha. If you have Gepard as a shielder in your team, consider picking up some Preservation and Remembrance Blessings.

How to Beat Svarog - World 4 Boss

Save Path Resonance and Ultimates for Summons

In the all of his phases, Svarog willl summon robots to aid him in battle. Focus on his summons before prioritizing Svarog since they can deal damage to your team, heal Svarog, and the arms he summons can capture your allies.

To take them out with ease, use your Path Resonance or Ultimates. Once they are out, Svarog should be easy enough to focus.

Free Captured Allies

In his 3rd Phase, Svarog summons robot arms that can capture your allies. The robot arms will inflict damage on them and you would not be able to use your captured characters, so try to take them out first when they hit the field.
