Phantasy Star Online Technique Shop Data

Return to Menu

Values are quoted in terms of weight used for calculations, commonly interpreted as a percent. However, this is more accurately stated to be the probability of appearing in the first tech spot in the shop. The probability of it appearing in the shop is a more complicated calculation. A good rule of thumb is that the probability of a given tech appearing in the shop is the probability of it appearing in the first slot (listed probability) multiplied by the number of tech slots. This is an approximation, but is a pretty good one. The calculation becomes infeasible when there are more possible disks, so the rule of thumb is useful.



Pre-Level 11 Shop Appearance Probabilities

Before level 11, the probability of seeing a given tech in the shop for a given visit is:

Levels 11-25 Shop Probabilities

The probability of seeing a given tech in the shop for a given visit is:

Level 26-42

For some techniques, there is a single level offered which depends on the player level. This is marked as "Lv/x" where Lv is the player's level and x is a number. This calculation rounds down to the nearest integer.
