From publisher blurb:
The Discerning Merchant's Price Guide is an organizational tool for magic items & pricing. It groups magic items together into categorical tables: melee weapons, armor, staffs, rings, and so on, similarly to how items were laid out in 3.5e. This should help DMs know exactly where to look and what their options are for handing out a given item. A reference column for book and page number for each item is also included, along with rarity, attunement requirements, and my own favorite feature: suggested item costs. Gone are costs that range from 5,000gp all the way to 50,000gp; you've now got a concrete number to start with that you can quickly adjust to suit the economy of the area at hand.
Version 5.0 includes the following new features:
99 magic items added to the tables
Weighted d100 columns next to every table to quickly roll a random item
Tables and tools for DMs needing to quickly roll up their own discerning merchant. This includes random tables for (a) shop names and significant details; (b) the merchant themselves, with their current mood, basic personality, and quirk; and (c) the economy of the shop, from its gold-on-hand to items in stock, from price modifications to what sort of bartering works best against the merchant.
