SR
Stamina
Analysis
Section titled “Analysis”Tier C. A fine budget Stamina SR to plug a gap in early Career, but any green SSR and an MLB rival bury it once your box fills out.
Pure Stamina filler for the back end of your deck. You run this in the slot you’d rather give to a real green SSR. The numbers land in the average-good range for an SR. Friendship Bonus caps at 20% with Mood Effect at 40%, and the Lv25 unique adds +10 to Friendship Bonus plus +20 starting Stamina. Specialty Priority reaches 60 at Lv40, which is the one stat doing real work here since it’s what earns Stamina rainbow sessions at all. Training Effectiveness is a sad 5% and the flat Stamina Bonus sits at 1, so raw stat throughput stays flat.
The hint kit points at Pace Chaser and Late Surger builds. You get Pace Chaser Savvy and Late Surger Savvy, both handy tactical greens, plus positioning hints like Prudent Positioning and Go with the Flow. Event skills are Sharp Gaze and Medium Straightaways. Free, modest, no gold heart to save you SP.
Then the depth chart kills it. Stamina is stacked on Global. Super Creek, Manhattan Cafe, even an MLB Satono Diamond all cover this role with better skills and more recovery. As a 0LB SR it just loses.
- Pros: 60 Specialty Priority, solid Friendship/Mood, free Pace/Late Surger hints, cheap to MLB.
- Cons: 5% Training Effectiveness, +1 Stamina, no gold skill, drowned out by every SSR stamina option.
Worth pulling if your stamina bench is genuinely empty. Otherwise it stays in the box.
