Phantylia the Undying in Honkai: Star Rail: how to win (commands and tactics)

Phantylia the Undying in Honkai: Star Rail is a weekly boss that was introduced in update 1.2 and is available after completing the corresponding story quests in Lofu Xianzhou. In this guide, we will tell you how to find this enemy and defeat him by choosing the best team.

How to access Phantylia the Undying and find Echoes of War

You will meet the boss for the first time in a quest "A brave dragon in a boundless ocean" from the chain "Hyperion Tower". In the task you have to defeat a weakened version of the boss - the strategy for fighting him has its own characteristics, it is described in the passage of the quest.

After that, you will have access to "Echoes of War: Seed of Immortality" with Fantilia - it can be found in the western part of the Scaled Gorge.

Stats of Fantilia the Undying

You can pass the test at 5 difficulty levels - depending on this, both the level of the boss and his characteristics will change:

• Level 1 - 47 boss level

• Level 2 - Level 57

• Level 3 - Level 66

• Level 4 - Level 75

• Level 5 - Level 82

At any level, Fantilia has 20% resistance to physical, ice, fire, and quantum damage, and 50% to Bind and Freeze.

In addition, the boss summons lotuses of Abundance and Destruction. Lotuses of Abundance are vulnerable to wind and imaginary damage, lotuses of Destruction - to quantum, imaginary and electric.

Featured Characters

As we can judge from the characteristics of the boss, characters with wind, electric and imaginary types of damage.

The fight lasts quite a long time - 3 phases - so a healer or a shield will be extremely useful. Best for this role Locha or Baylu: in addition to healing, they will be able to penetrate Fantilia's vulnerability. Baylu can also resurrect 1 hero per battle, which can come in very handy. Other healers and shields will be less effective due to Fantilia's resistance to other types of damage. If you still do not have the recommended Legendaries, we advise you to opt for the Pathfinder, who follows the path of Preservation - he can impose a small shield on the entire team and distract the boss to himself, preserving the health of the main fighters. Another budget option is Natasha - she can heal the entire squad with her superpower, which will be extremely useful at the beginning of the second and third phases of the battle.

Blade, Arlan or Jing Yuan, as well as free Dan Heng and Serval. If you don’t have them pumped enough and their damage is not enough, take Velt or Sampo as a sup-DD with periodic damage.

To increase the damage of damage dealers, we advise you to take Armor, Yukong, Tingyun or Silver Wolf. Hacker will be especially effective if not all the heroes in your squad can break through Fantilia's vulnerability.

Optimal Teams

An effective squad for the battle with Fantilia can be assembled from both legendary characters and starting ones available to all players. The following are examples of the best commands for battle:

Phantilia's combat and attack phases

• Achkhata: Rolling Thunder - Electrical damage to one target.

• Kalpa Approach – Selects one target and removes Vulnerability Protection from the Lotus of Destruction, inflicting the Blossom status on it.

Lotus immediately after being summoned have Vulnerability Protection, which means that it becomes much more difficult to damage them until Fantilia removes it. Here are their abilities and attacks:

• Black Prana Absorption is a debuff that reduces your character's maximum HP.

How to beat Fantilia

The fight may seem rather difficult and lengthy, but there are a few secrets that will help you deal with Fantilia faster.

First, do not forget about the help of the Eater of the Moon. His attack gradually builds up over the course of the battle, after which you can use it by clicking on the button on the right side of the screen. Roar of Heavenly Anthem will deal massive area of ​​effect damage and penetrate imaginary vulnerabilities.

Protect the characters at the end of each phase. Already when considering Fantilia's attacks, we noticed that when she enters a new phase, she deals a lot of area damage, which can cause you to lose your heroes. Make sure that towards the end of the phase, your fighters have shields or full HP, after which you can safely finish Fantilia.

Destroy lotuses. Focusing on the fight with Fantilia alone is not very wise, because the destruction of lotuses can give you nice bonuses. So, destroying lotuses of abundance, you get 3 skill points. By getting rid of the Lotus of Destruction, you increase Fantilia's damage and delay its effect.

Fantilia Achievements

In the battle with this boss, you can get a couple of achievements.

unhealthy look

This achievement is 5 jade from the Thirst for Battle section requires 5 times per battle to remove the Prana Drain debuff.

This can be done with Lochi's Cleansing Resurrection, Natasha's Soothe, March 7's Purification, or Armor's Combat Relocation skill. In the first three cases, be sure to make sure that your hero has the required ability activated in the "Traces" tab, otherwise you will not be able to get the achievement.

Weakening you get after attacking the Lotus of Destruction. To get the achievement, keep track of which of your allies is affected by the debuff and apply the skill on it.

All-round florist

This hidden achievement on 10 jade from the Battlelust section requires you to defeat Fantilia without destroying the Lotus of Plenty.

We recommend completing this achievement on boss difficulty level 1 with single target damage units in your squad. For example, Dan Heng should be included as a damage dealer, Tingyun and Armor as supports, and Baila or Natasha as a healer. If you don't have these heroes, make sure you don't accidentally use AoE attacks. Also, be careful when summoning the Moon Eater - it will attack all opponents.

You can still destroy Lotuses of Destruction, so in the second phase of the fight you can safely attack everyone.
