Luka’s damage over time effects cannot result in Critical Damage, so your focus when building him should be increasing Attack for maximum damage output. Additionally, prioritize Effect Hit Rate, Energy Regen Rate, and Speed to enhance his overall performance.

Best Team for Luka?

Despite his appearance as direct damage dealer, one of Luka’s significant sources of damage comes from bleeding damage over time effect. Therefore, it’s advisable to pair him with other characters who have similar damage over time mechanics.

When dealing with damage over time effects, Kafka is undoubtedly one of the best partners for Luka. Kafka’s skill effect that activates all damage over time debuffs enhances Luka’s bleeding effect even further. The key distinction between Luka and similar characters like Serval or Sampo is that she is strictly single target-focused and better suited for facing bosses.

Aside from that, remember to bring a support and a healer along with Luka. The support provides utility, while the healer ensures that no character goes down.
