What Combat Type is Luka?

Luka is a 4-star Physical character on the Path of Nihility, from Belobog, released in version 1.2.

What stat does Luka scale on?

Luka'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 Luka?

Along the Passing Shore is the closest fit on the data: it is a 5-star Nihility Light Cone with 635 base ATK at level 80, and its passive acts on ATK. Boundless Choreo is the best 4-star alternative.

Which relic set should Luka use?

Champion of Streetwise Boxing. Its 2-piece bonus is: Increases Physical DMG by 10%. Its 4-piece bonus is: After the wearer attacks or is hit, their ATK increases by 5% for the rest of the battle. This effect can stack up to 5 time(s).

Which Planar Ornament should Luka use?

Firmament Frontline: Glamoth. Its 2-piece bonus is: Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG. Planar Ornaments have no 4-piece bonus; the sphere and the rope are the whole set.

How much does it cost to max Luka'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 Luka E1 do?
