Overview

‘This battle is for the sake of saving the world!’

Arthur Pendragon (Prototype), the Once and Future King, charges into battle as the ideal of knighthood and the wielder of Proto Excalibur. Notable for his fantastic base stats, Proto Arthur is a Buster Saber with an anti-Giant niche who can be used for farming thanks to his good wave clear ability.

Arthur, like his Fate/Stay Night counterpart, packs Mana Burst to provide a hefty Buster buff for his NP turns. His sky-high base ATK, one of the highest of any Servant in the game, gives him strong base damage on command cards and contributes to his decent wave clearing. In addition, Giant Beast Hunt grants Arthur a very conditional, but very powerful, one-turn damage boost against Giant targets. Furthermore, it provides a handy 20% NP gauge, allowing for faster (even turn 1 with outside help) NP charging. Both of these factors build up to using and buffing his powerful AoE NP Excalibur, which further buffs itself with NP Damage Up (scaling with Overcharge) before it fires.

Unfortunately, like Proto Excalibur in lore, Arthur is bound by several restrictions that lower his overall performance. First and foremost, he finds his ideal use case somewhat muddled; Giant Beast Hunt only applies to uncommon Giant targets, who rarely appear in groups, yet Excalibur is less useful against single targets due its nature as an AoE NP. Arthur’s damage is further hamstrung by the short nature of his steroids; while he has multiple steroids, none last for more than one turn. Instinct also only provides a moderate sum of critical stars. Arthur’s overall sustained damage is therefore on the weaker end, which is problematic for a kit which is purely focused on offense and lacks any form of utility or support.. Last, but not least, he lacks any form of survivability aside from his good base HP, and will need defensive support for tougher fights.

All in all, Arthur is primarily a farming Servant, with occasional niche fights in which he can really flex his muscle. Though he doesn’t bring any fancy mechanics to the table, he will reliably clear waves for any Master.

Strengths

Strong Burst Damage

Between Mana Burst, his high base ATK, Instinct, and the in-built NP Damage buff on Excalibur, Proto Arthur has very good (AoE) burst damage potential. Masters can unleash a devastating single turn of powerful damage in order to clear a wave of enemies.

Good Farming Potential & NP Generation

Thanks to the 20% NP charge on Large Beast Hunting, Arthur can easily charge up Excalibur quickly. With the aid of a Starting NP Gauge Craft Essence or teammates, he can NP quickly to speed up farming significantly. In addition, his Quick and Extra cards possess noticeably strong generation potential, and his overall NP generation exceeds that of his Buster AoE Saber peers.

Anti-Giant Niche

Arthur packs a huge damage bonus against Giant enemies on a low cooldown, albeit for a short duration. Against many bosses of unusual size, he can really bring the pain - and in some Challenge Quests that feature multiple Giant enemies, he truly shines.

Weaknesses

Weaker Sustained Damage

Arthur doesn’t have a single steroid that lasts for more than one turn. Though his burst is high, his damage falls off dramatically outside of NP turns. With absolutely no Critical-based effects or similar boosts to his performance besides the small infusion of Critical Stars from Instinct, if enemies can survive Arthur’s Excalibur, he has very little left in the tank apart from his naturally high base ATK.

No Support, Defenses or Utility

Compared to many other AoE Saber options, Arthur offers very little to a team beyond hitting things. With every ability devoted to either direct damage buffs or indirect damage, he will need his teammates to cover all other aspects of the battle. Combined with his lack of survival abilities, finishing tougher fights with Arthur requires selecting the appropriate supports to back him up.

Conflict of NP and Niche

Though Arthur’s NP is AoE, his largest steroid, Giant Beast Hunt, only boosts his damage against Giant enemies - targets that tend to be found one at a time (barring a few exceptions) and in general don’t often appear as Lancers. Arthur will thus rarely be able to reach his (very high) damage ceiling due to this mismatch.

Level Up Skill Recommendation

Arthur’s gameplay usually revolves around Excalibur, so naturally Mana Burst stands out as a leveling priority in order to strengthen it as much as possible. Giant Beast Hunt helps amplify its damage against Giant targets, and also helps Arthur charge Excalibur more quickly. The NP charge itself is is unaffected by levels, but the shortened cooldown is highly beneficial for longer fights. Intuition can be left for last, as its values aren’t spectacular even if it does improve his burst damage potential.

  • Mana Burst is a straightforward Buster buff, and provides the biggest consistently useful steroid for Arthur’s burst damage and NP. Max it first.

  • Intuition is a relatively weak star generation skill, offering 15 stars at max level, which isn’t nearly enough to guarantee crits. It can be left for last, and it does benefit from a short cooldown.

  • Giant Beast Hunt is Arthur’s niche steroid and NP battery at the same time. Though the NP charge doesn’t scale, the anti-Giant damage scales strongly with rank, and reducing the cooldown is useful if Arthur needs to use his NP more than once in a fight. Max it second.

Craft Essence Recommendation

Arthur mainly wants to launch his Buster NP, the earlier the better, and pump up its damage.  This makes Starting NP Gauge and NP Damage Up Craft Essences good fits for him.  Starting NP Gauge can help release Excalibur as early as turn 1, and in general helps him clear waves and farm quickly. NP Damage Up is a straightforward boost to his NP burst turns, while Buster Up Craft Essences are comparatively only a slight buff to his NP damage but a bigger buff to his basic command cards.

  • Kaleidoscope / The Imaginary Element:  Kaleidoscope lets Arthur NP on turn 1 with no external support thanks to his NP battery. Other Starting NP Gauge CEs can help unleash his NP quickly if he gets further support from allies with NP charge abilities.
     
  • Golden Sumo / Holy Night Supper / Partake with the King / First Sunrise: Hybrid CEs work well if Arthur has a short time to charge his NP or receives additional NP charging support. Golden Sumo in particular gives the best multiplicative stacking with Arthur’s in-kit buffs.
     
  • The Black Grail / Heaven’s Feel: Pure NP Damage like that given by The Black Grail stacks additively with the NP damage buff on Excalibur, but still provides such a large numerical buff that it’s worth using to supercharge NP turns.
     
  • Limited/Zero Over / Verdant Sound of Destruction:  Despite Buster Buffs stacking additively with Mana Burst, Arthur’s high ATK means he enjoys the extra damage on his basic Buster command cards, and still does benefit on NP turns.
