Type in what the event shop shows → get your shopping list.
How many pirate coins you want to spend right now. Shorthand works everywhere: 37.9k, 1.2M.
For each stat, copy the three numbers straight off the upgrade row: your current value, what it goes to after one buy (the number after the →), and its price. Leave price empty to skip a stat.
Each purchase makes the next one pricier. These are measured values from the event — only touch them if prices in your game clearly grow faster or slower.
HP: not on the list on purpose — it adds zero damage. Buy it only if you're dying to bosses instead of running out of time.
Eggby (1M): that's a save-up decision, not a stat — the advisor stays out of it.
After a big spree, re-enter the new prices from the screen: the plan estimates price growth, the shop knows it exactly.
