Artoria Caster, affectionately known as Castoria within the Fate/Grand Order community, is a game-changing support Servant that every serious player needs in their arsenal. Introduced during the 5th Anniversary event, she has become indispensable for tackling challenging content and optimizing farming efficiency.

Unlike her Saber counterpart, Castoria doesn't wield a sword but instead amplifies your team's capabilities with powerful buffs, rapid Noble Phantasm charging, and enhanced survivability. As a premier Arts support, she transforms even average Servants into formidable forces when integrated into the right team composition.

Limited Availability

Before delving into Castoria's abilities, it's crucial to note that she is a limited 5-star Servant, appearing exclusively during select banners, typically linked to anniversary celebrations or major story chapters. If you spot her on a banner, consider using your Quartz, especially if you're aiming to build an Arts-focused team.

What Makes Castoria Special

In the diverse world of Fate/Grand Order, Servants possess varied abilities and roles. Castoria is designed for Arts synergy and comprehensive team support. Her skill set is tailored to enhance NP gain, amplify damage output, and facilitate rapid NP looping. She shines brightest when teamed with Arts-centric DPS Servants such as Space Ishtar, Summer Musashi, or Chloe.

Her third Append Skill is particularly useful as it boosts damage against Sabers, a class that can otherwise easily dismantle her support strategies.

Playstyle and Combat Tips

Position Castoria in the backline to maximize her support role. While she doesn't deliver high damage herself, her buffs significantly enhance the performance of her teammates. Deploy her Noble Phantasm frequently to maintain buffs and mitigate the risk of enemy NP removal effects.

During boss encounters, coordinate her invincibility with other defensive skills to avoid redundancy. In farming scenarios, time her buffs to ensure your DPS maximizes each NP chain.

Artoria Caster is more than just another iteration of Artoria; she's a top-tier support who has revolutionized combat strategies in Fate/Grand Order. Whether you're farming or facing tough challenges, Castoria is an invaluable addition to any team.
