Expected value across all drops. One rare, expensive drop raises it sharply. It is an average, not a payout. Computed from rAthena sell prices, which are disproven for Zero: usable as a ranking, not as an amount.

How this is calculated: Experience per HP = Base experience ÷ HP Zeny per kill = Σ (Chance × Sell price)

Where these numbers come from Three sources: the game client, the open rAthena collection and the community. rAthena is the framework but carries renewal data — drops, element, race and size match reliably, health points and experience differ in Zero. Where the client states its own numbers, those apply. Every value is labelled individually.
