How to Beat Phantylia the Undying

Bring a Shielder or Healer

Phantylia the Undying has three phases. With this, it's necessary to bring a healer for your team to survive until the end of the fight. In addition, you can also bring a shielder like Gepard or Aventurine if you need more survivability!

Healing and How to Recover HP

Cleanse Prana-Siphon Debuff

Phantylia the Undying summons Lotuses to assist her during the boss fight. Specifically, the Destruction Lotus it summons during Phase 2 and 3 will try to inflict Prana-Siphon to allies which decreases their Maximum Recoverable HP by 30% for 2 turns.

With this, don't forget to bring a character that can remove debuffs such as Luocha and Natasha when fighting Phantylia the Undying!

Use Cloudhymn Roar Effectively

During the fight, the Imbibitor Lunae will aid you in battle by allowing you to use Cloudhymn Roar.

Using Cloudhymn Roar may finish Phantylia the Undying's Lotuses and when used at the right time, will also break Phantylia the Undying's shield!
