What attribute is Ardelia?

Ardelia is a 6-star Nature operator of the Supporter class, from Rhodes Island, wielding a Arts Unit, released in version 1.0.

What stat does Ardelia scale on?

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

What is the best weapon for Ardelia?

Dreams of the Starry Beach is the closest fit on the data: it is a 6-star Arts Unit with 495 base ATK at level 90, and its skills act on ATK. Hypernova Auto is the best 4-star alternative.

Which gear set should Ardelia use?

Eternal Xiranite. Its 3-piece effect is: 3-piece set effect: Wearer's HP +1000. After the wearer applies Amp, Protected, Susceptibility, or Weakened, other teammates gain DMG Dealt +16% for 15s. This effect cannot stack. The 3-piece effect is the only set bonus a gear set has, and it needs three matching pieces; an operator equips four in all (Armor, Gloves and two Kits), so the fourth is free for an off-set piece.

How much does it cost to max Ardelia's skills?

Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× False Aggela among other materials. The Materials tab lists every item per level.
