System/Skills/Appraisal

Appraisal is a skill that allows the User to get information about other objects within the System.

General Information
Its efficiency changes drastically with every skill level. Level 1 Appraisal gives nothing but headache and just a name of scanned object. Frequent uses, however, can level up Appraisal quickly, allowing it to give more text information, show thorough stats and even targeted something other than pure material objects (for example, specific words shown by Appraisal earlier). It should be noted that a Ruler skill gives the option to block all Appraisal attempts[citation needed], and Appraisal can't scan objects that do not belong to the System (like gods or ancient robots).

Plot
Appraisal is the first skill learned by Kumoko. She relies on its effect for her survival.

Skill Evolution
At level 10 Appraisal gives all information on whatever it is used on, but does not have a skill evolution. The only exception to this is Kumoko's Wisdom skill, which was created by D[citation needed].

Trivia
Using Appraisal is actually harmful to user's soul[citation needed], so most humans prefer to use Appraisal Stones instead of developing this skill. Using the gem does not seem to harm the user or the gem.
