Good Fortune:
Lady Luck is always on your side when it comes to growing your coin pouch. For every creature that you gain gold based off of their challenge rating.
Merchant's Business:
At 3rd level, you have gained enough knowledge of the mercantile ways to choose a specialty for yourself. Choose between Wholesale and Retail as detailed below. You gain abilities in this subclass at levels 7, 11, 15.
At level 2, your mercantile ties make it so you can barter with magical entities. Because of this, you gain the ability to cast spells with your fantastic wealth. Cantrips: You start with three cantrips from the Merchant spell list. Spell slots: You pay gold to the magical entities in order to cast your spells. As such you have unlimited spell slots, but it costs gold to cast your spells. For each level of the spell, there is a different price: 1st Lv - 1gp, 2nd Lv - 5gp, 3rd Lv- 15gp, 4th Lv - 30gp, 5th Lv - 40gp.
