Strengths & Weaknesses

Cipher

Strengths
  • “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.
Weaknesses
  • 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.

Guinaifen

Strengths
  • Ultimate “Watch This Showstopper” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
  • “Blazing Welcome” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
  • Talent “PatrAeon Benefits” rolls a base-chance debuff that wants Effect Hit Rate—miss the stack conditions and the burst window feels empty.
Weaknesses
  • Several Guinaifen 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—Guinaifen alone cannot keep every wave fully stacked without a second DoT partner.
  • As a 4★ Nihility unit, Guinaifen is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
