At a Glance
Strengths & Weaknesses
Cipher
- “Yours Truly, Kitty Phantom Thief!” dumps a huge single-target Quantum multiplier into one elite—boss and Apocalyptic Shadow checks are where this Ultimate earns its trace levels.
- “Hey, Jackpot for the Taking” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “The Hospitable Dolosian” fires Follow-Up ATKs off ally Basics—damage keeps flowing even when Cipher is not the active turn.
- Several Cipher 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 “The Hospitable Dolosian” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Cipher’s off-turn damage.
- Spamming “Hey, Jackpot for the Taking” every turn without watching Skill Points strands the rest of the team—Cipher is often the SP sink.
Mortenax Blade
- Ultimate “Fornax Ex Corpore” spends HP as a deliberate self-damage cost—level this before polishing filler traces.
- Skill “A Rain of Blades Seals Fate” spends HP as a deliberate self-damage cost—the rotation wants controlled self-damage, not panic healing that cancels the state.
- Talent “All Karma Comes Due” fires Follow-Up ATKs off ally Basics—damage keeps flowing even when Mortenax Blade is not the active turn.
- Follow-Ups from “All Karma Comes Due” need allies who actually Basic ATK on schedule—freeze/CC on the team stalls Mortenax Blade’s off-turn damage.
- HP-spend skills mean Mortenax Blade can soft-lock if sustain is weak or if a healer tops them up at the wrong time and breaks a low-HP / Charge condition.
- Spamming “A Rain of Blades Seals Fate” every turn without watching Skill Points strands the rest of the team—Mortenax Blade is often the SP sink.
