Essence of theMerchant

You are able to assess the value of anything you see. Any object, living being or even a concept such as a person's emotions. This value can be equated to any other kind of value, whether it be physical currency, energy, mana, etc.

By paying the value, you can gain ownership over that thing, or cause an effect, such as spending mana to cast a spell.

You can sense, get in contact with and appear to or summon any entity you would like to bargain with.

You can negotiate any sort of transaction with ease, with knowledge of loopholes and clauses.

You can establish contracts for favors with other living beings in order to waive or reduce the value paid for the desired effect. This can include supernatural beings such as demons.

You may also act as a mediator between two parties, creating similar contracts and overseeing their execution impartially.

Once a contract is signed and sealed, you are linked to the other party or parties, and will know when they are fulfilling their end of the bargain. This link lasts until the contract is fulfilled or all sides agree to break it off (should you include such a capability in the contract).
