The Bazaar
Some of the things the entertaining man is selling have uses aside from their intended purpose. A subtle-smelling copper liquid which he claims is a perfume is actually the extract of a Desert Rose, a powerful magical reagent. In addition, the blue liquid he claims is imported from the frozen savages of the southlands may not have come that far, but it does appear to gain its scent from an undertone of magical Fundamental Ice. Finally, the most expensive bottle for sale is a pink liquid in an elaborately shaped bottle. He claims that it is a powerful anaesthetic, but Amirah can tell from the smell that it's properties are of a more magical nature, though it certainly does make her a teeny bit drowsy to sniff it. Medinah recongizes the magic signature - its a teleportation effect (a Fey Step Potion). The rest of the items are rather mundane, but they come in all sorts of colours, shapes, sizes and smells.
Mechanics:
SpoilerDesert Rose:
SpoilerGrowing only in remote desert oases, this yellow flower helps to maintain arcane and divine powers.
Price: 100 gp
Reagent
Power (Consumable): Free Action. Expend this reagent when you use a arcane or divine power of up to 5th level. You do not need to use an action on the following round to sustain that power (sustaining it for subsequent rounds does require the appropriate action).
Fundamental Ice:
SpoilerImmobilize your enemies with powers enhanced by this unmelting ice from the Southern Wastes.
Price: 200 gp
Reagent
Power (Consumable): Free Action. Expend this reagent when you use a power with the cold keyword of up to 7th level. One target hit is also immobilized (save ends). This reagent has no effect if the power already immobilizes the target.
Fey Step Potion:
SpoilerEncapsulated in a tiny vial of blown glass, this pink liquid lightly effervesces when uncorked and releases a sweet-smelling spray. Drinking the sour stuff grants the power to teleport.
Price: 200 gp
Potion
Power (Consumable * Teleportation): Minor Action. After consuming this potion, you can use a move action to teleport up to 5 squares before the end of your next turn. If you consume another fey step potion before the end of the encounter or before 5 minutes elapses (whichever comes first), you teleport 2 fewer squares than the last dose allowed you to teleport.
Scalytown
Hakhpur finds out little about the Merchant's Guild in this district. Though the magic shadow of Qamar sugar-coats his tongue, the locals seem disinclined to talk to him much. He learns, however, that he has already passed their assembly hall by the time he reaches Centre Circle Street. The kind old kobold who tells him this directs him back the way his came and instructs him to turn right when he reaches Inner Circle Street. You cannot miss it, my friend! he says with enthusiasm.
