Keen-Scentin' Concocter of Marvelous Draughts

The Concocter, which only is a very short version of an otherwise lengthy name from the myconid spore language, concocts potions which are then sold by his duergar partner Bellowgulp Bluefingers in The Black Pits.

The Concocter's palette of offered potions increases with the party's progress throughout the various "tiers" of the arena fights.

He sells at 145% of an item's base value and buys far more than only potions for 30% item value, at a depreciation rate of 5. Prices might be further modified through high charisma or an other-than-average reputation.
