Two structural facts make store pages legible.
1. Escalating price levels are a ladder, not a menu. The purchase rule, verbatim from a live bundle's rules text: "offered at different price levels; after the bundle has been purchased at the current price level, the next price level will be unlocked." So the $4.99 tier you see is the entry rung — buying it reveals the next, more expensive rung of the same bundle line. What this means in practice:
- Evaluate the rung, not the line. Each price level is its own purchase with its own contents; the first rung is usually the best value-per-dollar precisely because it's the hook.
- Know the ladder exists before you climb. The visible price is never the total cost of "buying this bundle event" — spending plans should be made against the full ladder, and stopping after rung one is a legitimate, often optimal, position.
2. The 0.75 Stone Law. Across measured reward and pack tables, resource bundles obey a fixed internal ratio: Food = Wood, Stone = 0.75 × Food. It has now been observed at three independent magnitudes in a single day — event caravans, event rewards, and a VIP pack reading 5,000,000 / 5,000,000 / 3,750,000. Uses:
- Sanity-check any table at a glance. A "5M food / 5M wood / 4M stone" listing is either a misread or an exception worth flagging — the law says 3.75M.
- Compare packs on one axis. Since the ratio is fixed, one resource number characterizes the whole block; compare packs by their food figure and you've compared the resource slice fairly.
What we don't claim: the law is an empirical invariant of measured tables, not a published rule — exceptions, if they exist, are exactly what the corpus watches for. So far: without exception.
