One last thing, whats the easiest and fastest way to get gold?

I explore but it doesn't give me enough gold so I can keep my pets lol I'm already running out of room.

Missions.

You can send pets on missions from the Barracks in either of the first two towns. Eventually you'll be able to expand the number of missions you can have going at once.

Each mission has a particular stat (health, strength, etc.) associated with it. Send a pet on the mission that's high in that stat, and you're pretty much guaranteed to get rewards once the mission time ends.

If you look on Advanced Search, go to the Search Pets section. Set level for 60-999, and change "Order By" to Sale Price - Ascending. There are a lot of high-level pets up for sale for only 1g. If you buy them and stick all their proficiency points into one stat, they'll make great mission pets.

Alrighty, thank you!
