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.

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.

Craft Essence Recommendation

Kaleidoscope

The Imaginary Element

Prisma Cosmos

Little Halloween Devil

Divine Banquet

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
