Overview

Contrary to how he is commonly depicted, Cu Chulainn is easily one of the hardiest Servants in the game, even when compared to higher rarity Servants. With a three-hit Evasion, Guts, as well as debuff removal and healing, Cu is able to survive most battles much longer than other Servants. Hence, he is an excellent option for last-stand scenarios and solo clears.

Unfortunately, Cu contributes little outside of his survivability. His instant kill is highly unreliable, while his damage and star generation are also nothing much to speak of. This means that he may become a liability in offensively-oriented teams - especially those who rely on having Servants die at the right time - and he is also not a good choice for farming. As a result, those with more developed Servant pools will rely much less on his niche. Still, when used correctly, he provides one of the highest benefits compared to the relatively low cost of investing in him.

Strengths

Excellent Survivability

Cu Chulainn is able to reliably survive the toughest of fights due to having one of the most survival-oriented kits in the game. This is mainly due to the sheer effectiveness of Protection from Arrows along with its low cooldown. With additional investments in the form of Grails, he is even able to single-handedly clear some of the game’s harder stages.

Versatile

More so than other Servants, Cu can be expected to perform reliably in a lot of different situations. This is in part thanks to his high survivability, as he is able to stay alive even against the hardest-hitting opponents. However, the things which truly solidify his versatility aspect are his self-debuff removal, as well as his single-target Noble Phantasm, the latter allowing him to deal decent damage despite his defensive kit.

Weaknesses

No Team Utility

As most of Cu’s kit is focused around keeping himself alive, he provides little to his team outside of his survivability. While his instant kill has the potential to end fights faster, it is highly unreliable and should not be relied on.

Average Offensive Capability

Due to his lack of any offensive buff, Cu’s potential in that regard is middling when compared to his alternatives (e.g. Cu Chulainn (Prototype)). This makes him somewhat unsuitable for players desiring faster runs and more offensive strategies.

Craft Essence Recommendation

  • Volumen Hydrargyrum: Volumen’s Invincibility buff can be stacked with Protection from Arrows, allowing him to completely mitigate incoming damage for a total of six times. The extra time means that he would be able to buy more time to wait out Protection from Arrows’ cooldown. Of particular note is that the Invincibility buff will be used before the Evasion.

  • Imaginary Around/Gandr/Holy Night Sign: With Cu’s three Quick cards, these CEs are able to improve his overall damage, especially with his NP. They also increase the amount of NP and critical stars generated by his Quick cards, which allows him to contribute more for the team.

  • Iron-Willed Training / Holy Shroud of Magdalene: Improving Cu’s already great bulk, these CEs allow him to last longer even against harder-hitting enemies.

  • A Fragment of 2030: Thanks to his survivability, Cu is a reliable choice to put 2030 on. Although he would not gain a significant performance boost with this option, it is a small price to pay considering his average capabilities outside of survival.

Level Up Skill Recommendation

  • Battle Continuation A

Normally a middling skill, Battle Continuation is essential for Cu Chulainn, as its usage would often be needed to buy time until Protection from Arrow comes off cooldown. However, this also means that Protection from Arrows should still be prioritized first.

  • Protection from Arrows B

This skill is easily Cu Chulainn’s best one, as a lot of his survivability is tied  to this skill. As the Evasion only expires when he is hit for a total of three times, it allows the skill to be used early on in a battle, thus getting a head start on its cooldown. As such, this skill benefits greatly from the cooldown reduction gained at skill levels 6 and 10. The additional defense up gained from this skill can also be highly valuable, especially if Cu is equipped with defense-increasing CEs.

  • Disengage C

Although this skill is arguably the least important of Cu’s three skills, the debuff removal and small amount of heal may help him survive in crucial moments. Leveling this skill would allow it to be readily available in most occasions thanks to its low cooldown.
