What Combat Type is Arlan?

Arlan is a 4-star Lightning character on the Path of Destruction, from Herta Space Station, released in version 1.0.

What stat does Arlan scale on?

Arlan's abilities multiply ATK. That is read from the scaling rows on the Skill and Ultimate, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.

What is the best Light Cone for Arlan?

I Am As You Behold is the closest fit on the data: it is a 5-star Destruction Light Cone with 635 base ATK at level 80, and its passive acts on ATK. A Trail of Bygone Blood is the best 4-star alternative.

Which relic set should Arlan use?

Band of Sizzling Thunder. Its 2-piece bonus is: Increases Lightning DMG by 10%. Its 4-piece bonus is: When the wearer uses their Skill, increases the wearer's ATK by 20% for 1 turn(s).

Which Planar Ornament should Arlan use?

City of Converging Stars. Its 2-piece bonus is: When the wearer uses Follow-Up ATK, increases ATK by 24% for 2 turn(s). When an enemy target gets defeated, increases CRIT DMG for all allies by 12% in the current battle. This effect cannot stack. Planar Ornaments have no 4-piece bonus; the sphere and the rope are the whole set.

How much does it cost to max Arlan's traces?

Taking one ability from level 1 to 10 costs 522,000 Credits and 1× Tracks of Destiny among other materials. The Materials tab lists every item per level.

What does Arlan E1 do?

To the Bitter End: When HP percentage is lower than or equal to 50% of Max HP, increases DMG dealt by Skill by 10%.
