Guide🔗

Labeled as NamuWiki community assessment (KR server). Subjective community opinion; no explicit S/A/B tier rating is stated.

Basically a slash-type dealer whose main tool is AoE skills. However, as an early/launch-era character he has no unique skill and his class is not especially special, so his dealing performance is mediocre. His ultimate Immovable Wisdom King Sword is rated as a reliable one-shot, but the problem is that Goyeongban, the staple accessory recommended for nearly all dealers, which reduces crit damage taken + heals on crit, is a perfect counter to it. Also, the "competing" skill Tempest Scharnhorst's Infinite True Light Flash is unbound by TP cost and effectively counts as defense-ignoring damage so its damage does not fall behind, leaving Arcion completely outmatched in the dealer race.

Perhaps because of this, lately his qualities as a buffer are getting more attention. At 5-awakening the TP needed for AoE skills drops by 1, and this also applies to AoE buff skills. So a 5-star-or-higher Arcion can use the TP-4 buff "Cry of Vigor", which spreads the "Vigor" buff granting an extra attack/skill, for TP 3, letting him spread the buff right at the start of turn 1. Vigor Black Prince can devastate opponents with ultimate Grima + skill or Asura Pachonmu, and Vigor Iyolin can break through the enemy's extreme defense and reliably take down the opposing Black Prince, so this is a very important buff and works as a big merit. Lacid can do the same role, but Lacid first has to receive a beneficial effect before he can use it on the starting turn, so Arcion, who can spread the Vigor buff with no help at all, has competitiveness. Especially in Knights War where you have to run 3 decks, Lacid is a bit lacking to use only as a Vigor member, so Arcion is an important support unit that lets you deploy Lacid in another deck. If run as a buffer, giving him Elizabeth's exclusive weapon Moonlight Rose, which additionally grants an attack buff to buff targets, lets you tack on an attack buff too, so it is worth considering.

Exclusive weapon is Durendal, a greatsword whose bonus stat is attack %, whose weapon skill increases AoE damage, and with an Arcion-only effect that reduces by 1 the cooldown of the skill with the longest remaining cooldown when a crit occurs on a combat attack. The limited effect applies only on combat attacks, but since the weapon skill boosts AoE damage, the single-target Immovable Myo-o Sword can trigger the cooldown reduction on a normal skill after use but does not receive the damage boost, and Arcion's normal AoE skills have low multipliers so even enhanced they do not become dramatically stronger. The design seems intended to support both AoE and the ultimate, but the result feels wishy-washy, neither one nor the other. Conversely, given to a character whose main tool is AoE rather than to Arcion, it can be very useful, so it is sometimes recommended to give it to Black Prince or to Nangcheon, whose main tool is repeated Meteor Annihilation Flash. (Community aside: "Just give Arcion the Meteor Sword.")

Awakening/Manifestation progression: Two tracks progress in parallel: Manifestation and Inner Cube. - Stage 1: Ultimate enhance 1; Stat enhance 1. - Stage 2: Unique passive enhance 1; Stat enhance 2. - Stage 3: Ultimate enhance 2; Artifact obtained - Hellkite's Gaze, Warrior's Essence, Will of the Fatal Blow. - Stage 4: Unique passive enhance 2; Artifact enhance 1. - Stage 5: Ultimate enhance 3; Artifact enhance 2. - Stage 6: Unique passive enhance 3; Artifact enhance 3. Ultimate Immovable Wisdom King Sword damage scaling by ult enhance level: 200% at first acquisition, 230% at max Awakening, 260% at max Manifestation. All: always 99% chance to crit, cannot be counterattacked, cannot be guarded. Note: the artifact table below lists Assist/Combo Link, Attribute Overload, Warrior's Essence, while stage 3 text names Hellkite's Gaze, Warrior's Essence, ?. Only Warrior's Essence appears in both.
