Overview

Often overlooked due to his status as a 1 Star Berserker, Asterios is one of the prominent members of Stall teams thanks to his amazing debuff Noble Phantasm. While he is hard to set up properly and requires a specific team composition, once he gets going he can completely debilitate any boss in the game with repeated use of Chaos Labyrinth.

Outside of this particular usage however, Asterios is quite bad in other aspects. Due to being a 1 Star Rarity Servant, his base stats are extremely low, hampering both his offensive capability and survivability. His skillset is nothing truly spectacular, and while he can be used as a Buster Critical Damage Dealer, his flaws will hold him back tremendously without proper team support.

All in all, Asterios is similar to most other low rarity Servants in that he occupies a particular niche that not many people will use, but is extremely effective at that niche. If you are a fan of stall teams in general and have the other pieces to build a team around Asterios, he can get you through some of the toughest battles in the game.

Strengths

Extremely powerful Debuffing Noble Phantasm

Chaos Labyrinth is one of the best Debuffing Noble Phantasms in the game, allowing Asterios to cripple enemies to help his entire team.

This Noble Phantasm also has tremendously long duration, allowing Asterios to stack these debuffs multiple times over the course of a battle.

Once upgraded, during the turn of its use, most enemies will not be able to do any damage due to the additional one-turn debuff.

Can function as a Critical Damage Dealer

Upon completing his Rank Up quest, Asterios gains access to Labrys of the Abyss, allowing him to gather Critical Stars reliably for one turn. When combined with his heavy Buster-centric deck and his first skill, he can deal a lot of damage during that turn.

Weaknesses

Extremely frail

Asterios has very poor survivability on his own due to his low HP and his class. He can get killed with one critical hit from most enemies of the same level.

He also does not have any tools to avoid being focused by bosses (Dodge / Guts / Invulnerability).

This make him extremely reliant on his Noble Phantasm and his teammates in tough challenges.

Requires specific team compositions to work

Asterios does not work well alone. His niche requires the team to facilitate his NP spam through helping him get to 100% NP bar constantly and in addition his team must also be able to protect him from being killed for the first few turns.

Craft Essence Recommendation

Asterios shines when used in a Arts Stalling teams due to his NP. Stacking his NP makes his enemies completely useless, so Asterios's main priority in terms of what he wants from a CE is either starting NP gauge to get off his first NP as soon as possible to get him going, or a way to increase his NP gain.

  • Kaleidoscope / Imaginary Element: Allows Asterios to quickly get to 100% NP bar to use his first NP which is the most important one to get him going
  • Little Halloween Devil: Similar to Kaleidoscope and Imaginary Element, however this CE also helps Asterios beyond his first NP use with its increased NP generation rate
  • Prisma Cosmos: For long battles this CE is the best in term of NP generation, and allows Asterios to steadily gain NP even when he is not attacking
  • Divine Banquet: A lesser CE compared to other choices and provides a solid NP generation boost, but its effect is not as profound due to Asterios's lack of more than one Arts card

Level Up Skill Recommendation

Despite being a 1 star, Asterios actually makes a fine damage dealer due to a combination of his skill set and Noble Phantasm.

  • Monstrous Strength is his bread and butter damage skill and is also the most straightforward to use thanks to its long duration and low cooldown when maxed.
  • Both Natural Demon and Labrys of the Abyss are worth maxing. Natural Demon makes him incredibly tanky after he fires off his NP while Labrys of the Abyss adds some much-needed firepower for him to excel with.
  • On the whole, Labrys of the Abyss comes much later since it requires his Rank Up quest, but its worth more to raise thanks to its good burst potential.

Nonetheless, if players are keen on using Asterios, maxing all three of his skills are highly recommended as they are all great for him.

Suggested Servant Synergies

  • Chevalier d’Eon: Much like for Vlad, d’Eon shines as an Arts support tank who has the Buster cards to form Buster chains with as well. d’Eon’s taunt abilities provide Asterios the safety to build his NP gauge and strongly debuff the enemy team. d’Eon’s NP debuff stacks nicely with Asterios’s, leading to even more survivability. Georgios does much the same role; Asterios and Georgios are popular choices for people doing “Bronze Servant Only” runs.

  • Mata Hari: Mata Hari’s debuffs stack nicely with Asterios's for both amplified damage and reduced damage taken. Post interlude/Rank Up, Asterios’ debuffs will stack with Mata Hari’s debuffs for a potential whopping 105% defense down and 85% attack down. With defense buffs from a third servant, it is possible to completely negate an enemy’s NP damage.

  • Hans Christian Andersen: Using Asterios as an attacker is possible post-Rank Up due to the skill he receives, “Labrys of the Abyss”, which increases Asterios’s Buster performance and critical star absorption. Asterios can combine his own buffs with Hans’s crit damage buff and stars to bring out strong damage for a single turn.
