Devilish Deal

You summon a shop window where an imp will conduct an exchange with you. The imp can converse with you, but is unwilling to haggle or negotiate prices. The imp and window are incorporeal and can only be interacted with to conduct an exchange. You can conduct one of the following exchanges:

• Buy. You can exchange gold for one material spell component (Such as a pearl worth 100+ GP) of equal or lesser value.
• Trade. You can trade items that have a predetermined GP worth (Such as equipment, art objects, gems, or magic items) for one material spell component of equal or lesser value.
• Sell. You can sell one item that has a predetermined GP worth for gold.
• Exchange Essence. You can relinquish your life essence in exchange for one material spell component. When you give your essence, you can choose to receive up to 5 levels of exhaustion. The worth of your given essence is 25 GP for each level of exhaustion you gain, multiplied by your character level. You can have only one item received this way at a time; if you exchange essence and already have a component from a previous essence exchange the first one immediately vanishes.

If casted as a ritual, you can make a number of exchanges equal to your proficiently bonus. This increases the duration by 10 minutes for each exchange after the first.
