Keen-Scentin' Concocter of Marvelous Draughts

The Keen-Scentin' Concocter of Marvelous Draughts, or just the Concocter, are short versions of an otherwise lengthy name from the myconid spore language. His main purpose in life is to come up with substances that provide benefits to the imbiber or havoc to their enemies. He provides those in the form of potions, sold in cooperation with his common tongue capable sales agent Bellowgulp Bluefingers.
==Stores==
There are four versions of the Concocter and related stores:
# The Black Pits version, which has three different tiers resulting in three stores
# Siege of Dragonspear version
# Throne of Bhaal version in Neera's companion quest Destroying the Order of Eight Staves
# Gladiators of Thay version (only one store, no tiers; same as Throne of Bhaal except for stock numbers)
===The Black Pits===
The Concocter's palette of offered potions increases with the party's progress throughout the various "Tiers" of the arena battles. Items from earlier Tiers will be still available later and previously purchased ones restocked. The basics of the store remain the same, such as markups, deprecation rate and services.
===Siege of Dragonspear===
The Concocter and Bellowgulp Bluefingers are located in the northern portion of the Underground River. For this store:
*he sells twenty-six items including one only found in this game (marked with )
*has a good stock of most items
*does not ignore reputation
*charges a standard deprecation rate of 5%.
===Throne of Bhaal Enhanced Edition (Neera)===
During Destroying the Order of Eight Staves, you come to the staging area in Dennaton's mansion. This has the same merchants with more or less the same offering, however with quantities adjusted. In the Concocter's case:
*he sells two more items (marked with )
*reduced stock of most items
*does not ignore reputation
*charges a standard deprecation rate of 5%.
===The Black Pits II: Gladiators of Thay===
In this edition of The Black Pits there are no tiers when it comes to store stock. All stores have the same stock. More expensive items are instead obtained by donations from the audience.
The store ignores the party's reputation when calculating prices as there is no way to alter the reputation of the party in the pits. However, its prices are generally 25% cheaper than is standard in Baldur's Gate II and he doesn't charge a deprecation rate, which is a little compensation.
