At a Glance
Strengths & Weaknesses
Kafka
- Ultimate “Twilight Trill” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
- “Caressing Moonlight” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Gentle but Cruel” fires Follow-Up ATKs off ally Basics—damage keeps flowing even when Kafka is not the active turn.
- Several Kafka effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
- Follow-Ups from “Gentle but Cruel” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Kafka’s off-turn damage.
- E0 without “Patience Is All You Need” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Nihility carries—plan the cone before deep eidolon hunting.
Luka
- “Coup de Grâce” dumps a huge single-target Physical multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
- Skill “Lacerating Fist” rolls a base-chance debuff that wants Effect Hit Rate—that is how Luka applies pressure between Ultimates.
- Talent “Flying Sparks” seeds or detonates DoT statuses in the same cast—miss the stack conditions and the burst window feels empty.
- Several Luka effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
- DoT damage needs other appliers or long-lived statuses on the field—Luka alone cannot keep every wave fully stacked without a second DoT partner.
- As a 4★ Nihility unit, Luka is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
