Overview

Cu Chulainn (Prototype)

RarityCostClass
3★7Lancer
Lancer
Rating9/10

Proto-Cu Chulainn is a solid 3 star Lancer, with skills in both damage increase and survival. When compared to his S/N counterpart, he lacks survivability since he does not have the Battle Continuation or Disengage, but has significantly higher damage potential due to his crit damage buff. Aside from these differences and minor stat difference, both Cu Chulainns’ NP are equivalent to each other.

Pros

  • High Survivability: Though he lacks the guts and heal from his S/N counterpart, Proto-Cu still has the fundamental skill that represents Cu Chulainns’ survivability in F/GO series, Protection From Arrows. Which gives Proto-Cu a good survivability skill.

  • Crit Damage: Something that distinguishes Proto-Cu from the original is that Proto-Cu has a skill that actually contributes to his damage output. He can increase his crit-damage up to 45%, which synergises well with the DEF reduction on his NP during NP brave-chain.

  • Simple requirements: Proto-Cu’s ascension requirements and skill level requirements are comparably easier than his original, requiring relatively more common materials. Only materials to watch out for is the Chaos Talons for his 3rd and 4th ascension, and 16 Octuplet Twin Crystals in his 8th skill reinforcement. It also helps that there are little stat improvements between Lv 60~70 window, which means Lv 60 can be where Cu Chulainn’s upgrade can effectively end, saving materials in the process.

Cons

Third skill: Beast Slayer gives extra damage to ‘Beast’ type enemies. Ironically, there is no Archer-type servants with ‘Beast’ characteristics notwithstanding, the enemy pool is very small, making the point of the third skill almost obligatory. After strengthening quest, Beast Slayer gains star gather increase, which greatly increases merit of the 3rd skill, but it is yet to be implemented.

Strategies & Tips

Proto-Cu’s strategies are not that different from the original. He survives using Protection from Arrows, and deal damages, but this time, with more damage output thanks to the crit-damage increase from the first skill.

As a crit support, Anderson has many skills with him that can assist Proto-Cu, it also helps that Hans has heal, which will help Proto-Cu in surviving.
Leonidas
Leonidas
Being a taunt tank, helps saving Proto-Cu in a bind, but his NP also generates star, which will help in Proto-Cu’s crit damage.

Noble Phantasm

Proto-Cu’s Noble Phantasm does not differ from the original, it has the same scaling, same instant death chance, and DEF reduction. But Proto-Cu can utilise the DEF reduction more since he can dish out more damage than original.

Skills

Upgrade Priority

1>2>3
This priority order focuses on damage, since critical damage increase can reach up to 45% by skill level 10, those who want more damage per turn should focus on Rune Magic more than other skills.

2>1>3
This priority order focuses on survivability. When maxed, Protection from Arrow has 5 turn cool-down, which means, unless used solo, Proto-Cu can use Protection from Arrow once he’s evades have been cleared, boosting his survivability.

In both cases, Beast Slayer takes lower priority due to lack of its usefulness.

[After Strengthening Quest] 1>3>2
After strengthening quest, which adds a star gather increase for Beast Slayer, to maximise his potential damage output, maxing the skills by this order is recommended.

Not much can be said about Cu Chulainn’s command card, though he has two quick card and a quick NP, he cannot generate much star by his own since he has little attack star generation rate. But since he has two buster cards, when crits happen, he can potentially deal a lot of damage.

This is so late as to be near useless, but the intermediate tea set collection does in fact drop ...
They add more items to the events as they become drops in the singularities. Gears and pages will...
It worked very well! Thanks :)
