I'm doing a bit of farming and I recently bought a hero (common gen 1 warrior/warrior). Here are his stats: https://postimg.cc/bSQ5VGwM. All I've been doing is quests alternating between foraging and fishing because the mining quest says "coming soon."

What else should I be doing in the game? I don't have more money to buy more heroes right now, but I know that more heroes lead to greater quest rewards. I heard that you can summon another hero as long you own one by renting another hero, but the prices are so expensive. It seems cheaper to just buy another hero.

What kind of heroes should I look for if I'm to summon with my warrior? What kind of heroes should I look for if I'm to buy another hero? It seems like buying is cheaper than summoning, so why would anyone summon?
