Artoria Caster 'Castoria' Guide: Skills, Synergies, Top Teams

Author : Penelope Apr 05,2025

In the vibrant world of Fate/Grand Order, Artoria Caster, affectionately known as Castoria, has emerged as a pivotal support Servant, revolutionizing gameplay since her debut during the 5th Anniversary event. For players aiming to conquer the game's toughest challenges or streamline their farming strategies, Castoria is an indispensable asset.

Unlike her Saber counterpart, Castoria doesn't wield a sword; instead, she empowers your team with formidable buffs, accelerates Noble Phantasm (NP) charging, and extends the lifespan of your allies. As a premier Arts support, she transforms even moderately powerful Servants into formidable forces when integrated into the right team composition.

Limited Availability

Before delving into Castoria's capabilities, it's crucial to note her status as a limited 5-star Servant. She appears exclusively during specific banners, typically linked to anniversaries or major story chapters. If you spot her on a banner and are building an Arts-focused team, it's wise to consider using your Quartz to secure her.

What Makes Castoria Special

In Fate/Grand Order, Servants vary widely in their abilities and roles. Castoria stands out with her focus on Arts synergy and comprehensive team support. Her skill set is designed to enhance NP gain, amplify damage, and facilitate rapid NP looping. She shines brightest when teamed with Arts-centric damage dealers like Space Ishtar, Summer Musashi, or Chloe.

Among her Append Skills, the third one is particularly useful, as it boosts damage against Sabers, a class that can otherwise easily penetrate her support defenses.

Playstyle and Combat Tips

Castoria is designed to bolster your team from the backline. While she doesn't inflict significant damage herself, her buffs significantly enhance the performance of her teammates. Deploy her NP frequently to maintain continuous buffs and mitigate the risk of enemy NP removal effects.

In boss encounters, strategically stagger her invincibility with another defensive skill to maximize protection without overlap. For farming scenarios, time her buffs to ensure your DPS maximizes the impact of each NP chain.

Artoria Caster, or Castoria, is far more than just another iteration of Artoria. She's a game-changing support who has reshaped combat strategies in Fate/Grand Order. Whether you're tackling high-difficulty content or optimizing your farming runs, Castoria is a valuable addition to any team.
