• Xane’s Joker's Wild meant that his visible stats will not contribute to combat. However, it is still used as potential stat checks against the enemy. This meant that his low visible stats can be manipulated to the player’s advantage. By intentionally lowering Xane’s Attack and Speed using flaws, this enables Xane to dodge the full effect of Void Tome, which is a common defensive mythic in Light / Dark Season in Aether Raids.
• With that in mind, he can go for other Passive B such as Special Spiral or Lull Atk Spd. If a player has intentions of merging Xane, he will exceed 35 SPD due to the flaw correction of merges by the time he got his 2nd merge. Without the flaw in speed, he will exceed the threshold after a single merge. At that point, Xane will have to run Null Follow-Up to avoid incurring the wrath of Bramimond.
• As Joker’s Wild mandates an ally to remain within 2 spaces of Xane, Xane is likely to be more capable in the enemy phase. Hence, the focus of the build is to be able to take as many hits as possible. For the special, Sol synergizes with Spiral as it enables Xane to repeatedly heal after Xane gets his first Sol activation, while Noontime is the more plug-and-play option that works with most builds. Seal wise, Spd Res Solo further improves Xane’s durability in a predominantly magic-hitting environment in Aether Raids Defense while preventing more doubles from speed checks, while Mirror Stance is the more offensive option.
• Naturally, Pulse Smoke is mandatory against potential Infantry Pulse users, with Atk Smoke as more of a budget substitute. Joint Drives are also a good proposition as he would need to be within 2 spaces of his allies at almost all times.

Passive C: Joint Drive ATK / Infantry Hexblade

Sacred Seal: Atk/Def Solo / Sturdy Stance

• With a base stat total of 166, Xane is capable of reaching an effective BST of 170 after a merge if he goes for his super assets in defense. This opens up his Passive A slot to help him in combat. 
• Due to the prominence of physically hard hitting Legendaries such as Legendary Chrom, Legendary Alm, and Legendary Edelgard, it is likely for ATK and DEF to be more useful in Arena. Close Foil will grant him the ability to tackle melee foes while giving ATK and DEF. Atk/Def Solo and Sturdy Stance is also chosen for the same reason.
• Similar to many arena builds, SP costs is part of the consideration for an arena build. Specifically for Xane, as there are no Passive B that costs 300SP, there is no incentive in running a higher SP cost passive such as Joint Drive ATK at least in terms of Arena Scoring. 
• While Joint Drive ATK is probably his best option in Passive C to maximize his damage output, Infantry Hexblade is an interesting option to provide support to his allies due to most Legendaries having rather lopsided defenses.
• Due to Armors being prominent in the higher arena tiers, guaranteed follow-ups are pretty common. Hence, Null Follow-Up is likely to be rather useful to tackle such threats.
• The rest of the skills are not pivotal to how the build works. The only requirement being a skill with the maximum SP cost (500 SP for Specials, 400 SP for assists).

• In Aether Raids Defense, Xane’s weapon will likely be in full effect at the start of the battle as the team is restricted to the top 2 rows of the map. This meant that he is potentially durable and deadly depending on the allies used around him. Xane being a colorless mage also help massively in terms of consistency.
• However, due to the 2 space restriction, Xane’s weapon can be inconsistent during the defense team’s player phase. Hence, when using Xane in Aether Raids Defense, players will have to consider other means to meet his weapon requirements. This can be done by manipulating the AI using rallies, heals or dances.
• The predominant role for Xane in this build is to absorb player phase pressure using his borrowed bulk from Joker’s Wild. Speed and Defense is the primary focus of this build due to the prominence of physical units in Aether Raids Offense, however it is largely flexible depending on the targeted match-ups that Xane is facing.
