Strengths & Weaknesses

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.

Welt

Strengths
  • Ultimate “Synthetic Black Hole” hits every enemy on the field in one cast—level this before polishing filler traces.
  • Skill “Edge of the Void” rolls a base-chance debuff that wants Effect Hit Rate—that is how Welt applies pressure between Ultimates.
  • Talent “Time Distortion” When hitting an enemy that is already Slowed—ignore it and Welt plays like a worse generic Nihility unit.
Weaknesses
  • Several Welt effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
  • If Energy or Skill Points starve “Synthetic Black Hole”, Welt spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
  • Spamming “Edge of the Void” every turn without watching Skill Points strands the rest of the team—Welt is often the SP sink.
