This skill will allow you to appraise an item's value. Also, when getting a large amount of treasure from the ground, you can set a value threshhold of what to take and what to leave. In this case, you will make an attempt to evaluate an item's worth before picking it up. Higher skill percentages will increase the accuracy of your appraisals.
Usage: use appraise at [item] — or — use appraise at threshold [value]
EX: 'use appraise at threshold 1000' will set a level of 1000gp. When you use 'get all' or 'get all [blah]', you will try to pick up those items that you succeed in appraising as worth more than 1000gp.
