Table of Contents

Overview

Proto Cu is, in essential, a much more offensive version of normal Cu Chulainn. Trading Battle Continuation and Disengage for the ability to do critical damage reliably and increased damage against Beast type enemies allow him to serve as a great budget damage dealing Lancer. Beast-trait is a quite common trait amongst frequently appeared enemies, such as Chimera, meaning Proto Cu will prove quite useful for these type of enemies and will only become more valuable as the game goes on. And while he does not have Guts, Proto Cu is still extremely tanky thanks to Protection from Arrows and is more than adequate for him to find a place in tough challenges.

Proto Cu however is not without flaws, as he has a somewhat awkward deck of BBQQA which hampers his NP generation rate while does not really contribute much to his Star generation rate either. He also does not contribute much to the team in term of buffs or debuffs, and while he is a good Servant independently, he needs heavy support to reach his full potential.

Strengths

  • Hard to kill thanks to having Protection from Arrows
  • Great damage potential for a 3 Star Servants thanks to possessing both a Critical Damage increase and Star Absorbtion buff
  • Is a great choice when battling enemies with Beast trait (a quite common trait that's often found in events/daily maps)

Weaknesses

  • Awkward card deck for NP generation combined with fairly normal NP generation rate means he often need support to get to 100% NP bar
  • Lack of Attacks or Card Performance boost to improve his NP damage output and often rely on Critical Hits to deal meaningful damage, making him more dependent on team support
  • Mediocre Star generation capability despite having a light Quick deck due to low hit count on his cards

Divine Protection from Arrows is the claim to fame for both Cu Chulainn and it is what gives them incredible tankiness for hard battles. Thus, you'd do a disservice not leveling it first.

Afterward, Beast Slayer is better than Rune Spell as it gives Cu Chulainn Prototype a unique niche against certain enemies. Furthermore, in the long run, it is also a great offensive skill after the Rank Up due to the crit stars absorption.

Rune Spell is his least important skill, not because it is bad, but because it isn't particularly good on him until he receives his crit star absorption component on his 3rd skill, so it should be leveled last.

Craft Essence Recommendation

Being a strong survivalist and critical damage dealer (once he gets his Rank Up quest), Cu Chulainn Proto appreciate any form of Quick card performance boost as well as a critical damage boost.

  • Knights of Marines / One Summer / Chaldea Anniversary - These are mixed Starting NP Gauge / Quick Damage Up CEs that allow him to start battle closer to being able to unleash his NP, while also providing a small offensive boost.
  • Imaginary Around / Gandr - the basic Quick card booster CEs are perfect for him as he has a light Quick deck (BBQQA)
  • Guda-O / Holy Night Sign: Craft Essences that give him two out of several stats that he want
  • Water Shine / Gem Magecraft: Antumbra / Knight's Dignity: For team that make Cu Proto the main Critical Damage Dealer, these provide boosts to his critical performance

Profile

Character Info

In Celtic mythology and the Ulster Cycle, there is a great hero who stands above all.
A "Child of Light" born of the blood of the Sun God, Lugh.
Also known as the Guard-Dog, he seems to be the same individual as the Lancer that is summoned with the same True Name.
However, his body and mental age seem to be a bit younger than "the other one."

Profile 1

Height/Weight: 184cm, 71kg
Origin: Celtic Mythology
Region: Europe
Alignment: Lawful-Balanced
Gender: Male
Can use Rune spells just like "the other one."

Profile 2

He's a wild but cool kind of guy.
Even though he won't judge between justice or evil and decide which one is better, he cares deeply about being just in the world.
But he isn't mature enough to accept the many unfairnesses that occur in the world.
He's a creature tamer, and has a great affinity for dogs.

Profile 3

Compared to the Lancer summoned with the same True Name, he wears heavy armor.
Despite this, his dexterity parameter is A+, surpassing "the other one."
It's not that he's more capable, but that he's younger, and overenthusiastic which causes several differences between them.

Profile 4

[Gáe Bolg]
Rank: B/B+
NP Type: Anti-Personnel/Army
The Spear which Reverses Causality.
The scarlet spear and related arts which he received from his mentor, Scáthach.
Capable of Anti-Personnel Thrusts and Anti-Army Throws.

Profile 5

Compared to the other Lancer, he has a bit more affection for his teacher, Scáthach.
It's unknown whether this is due to his age or how much time has passed.
It's true he cannot accept the unfairness of the world, and the fact that it's all shades of gray, but...

Profile 6

He probably thinks it's commendable that his Master is attempting to correct human history, and most likely wouldn't mind lending a hand. However, you must be careful, as he may not respond the same as the Lancer with the same True Name.

Bond Level 2 There's another Cú Chulainn?
Well, I can't say I'm surprised.
I mean, humans and Heroic Spirits are different in all kinds of ways.
Bond Level 3 You won't necessarily summon the same Heroic Spirit of the "same hero" every time.
What? You can change to me any time.
Bond Level 4 Take humans, for example.
Even they can turn into different people over time, you know?

Actually, never mind.

I like dogs, myself.
Especially hunting dogs.
Dislikes There's not much I hate. I've got nothin' but bad luck when it comes to women, though.
But that's just part of a beautiful woman's charms. Nothing better than a little danger, am I right?
About the Holy Grail Have you heard of Dagda's Cauldron?
I feel like it's the original Holy Grail.
What do you think?
During an Event Looks like an interesting festival has started. Might as well join in.
