What the current evidence supports
The public references expose the shop and monster-pool systems, while the local Critcap snapshot exposes how often units, trainers, and trinkets occur in Master late compositions. Those are useful signals for research and comparison.
Review boundaryThere is no approved video walkthrough for a general reroll route in this first phase. Treat exact gold thresholds and stage-by-stage spending rules as open research.
Build a decision record
- Record the comp, patch version, bracket, and sample before comparing a rate.
- Keep play rate separate from strength. A popular line may be easier to find or simply more visible.
- When reviewing a reroll claim, capture the shop state, board state, and next battle outcome together.
