Stamina
Analysis
Section titled “Analysis”Tier B. A solid Friendship-type stamina SSR that does its job, but Super Creek and Kitasan Black own the slot, so only build it when those benches are empty.
Friendship-type stamina card, so the plan is simple. Park it on the stamina tile and farm rainbows. The fundamentals hold up. Friendship Bonus tops out at 20% by Lv45, Training Effectiveness reaches 10% at Lv50, and Specialty Priority climbs to 50, so Diamond keeps landing on stamina to feed the bond. Mood Effect is the standout: 40% from the support effect with another +15 from the Lv30 unique. Stack a maxed mood and the whole deck feels it. The unique also adds +15 Initial Friendship Gauge on top of the base 25, so you start almost bonded and hit rainbows quick.
The skills are where it sags. Hints push front-runner recovery and conditionals like Firm Conditions, Tether, and Studious instead of the heavy stamina recoveries you want capped. Iron Will and All I’ve Got come off the events, which is fine. None of it makes you reach for the pull.
The real issue is the neighbors. Super Creek and the Kitasan stamina SSR both beat it on raw recovery and skill quality, and most builds only slot one or two stamina cards anyway.
- Pros: 20% Friendship Bonus, big mood stacking, strong starting bond, high Specialty Priority.
- Cons: weak recovery hints, no marquee proc skill, stuck behind Creek and Kitasan.
Thin stamina bench? Worth a slot. Own either premium card? It sits.
