Higher Grade Knowledge Gain
Knowledge grades range from the highest grade (S) to the lowest default grade (C), which are obtained according to a specified probability formula.
The knowledge that you have acquired is graded according to the probability formula listed below.
If you fail to acquire higher-grade knowledge, the probability formula for acquiring knowledge of a grade one level lower grade is applied, and this is repeated until the final grade is determined.
(Example: Failure to acquire S grade knowledge -> Activation of A+ grade knowledge acquisition probability formula -> Failure to acquire A+ grade knowledge -> Activation of B grade knowledge acquisition probability formula - Repeated until final grade is determined)
Knowledge Acquisition Probability Formula
Basic knowledge acquisition probability: Items such as Ellen Glasses and Weenie Elixir (which have the "Chance to gain knowledge increases by +50%" disclaimer in the item description) proportionally increase the probability based on the acquisition rate for basic knowledge.Knowledge Acquisition Probability Formula by Grade
- S grade knowledge acquisition probability: 1% + @
- A+ grade knowledge acquisition probability: 6% + @
- A grade knowledge acquisition probability: 16% + @
- B grade knowledge acquisition probability: 46% + @
- C grade knowledge acquisition probability: Obtained after failure of all other grades.
※ @: Represents items such as Round Earrings and Looney Elixir, (which have the "Increased chance of acquiring higher-grade knowledge when acquiring knowledge" disclaimer in the item description), that increase the probability of acquiring higher-grade knowledge.
Example: When wearing Round Earrings, the chance of acquiring S grade knowledge increases to 6% (1% + 5%).
