# Gameplay Much of the gameplay in Song of Rising is centered around Heroes, the utility-based NFTs that can gather resources with Professions and will eventually be able to participate in combat quests and even PVP. You can visit the hero market to buy Heroes and you can learn more about what makes each Hero unique in the Heroes section of this guide. If you don't have enough RUBY yet to purchase a Hero, that's ok, too! You can invest what you do have through the RUBY (DEX fee sharing) or in the Farms (liquidity pooling) to begin earning more RUBY. Of course, you'll need to visit the Marketplace to trade for RUBY in the first place. The possibilities for gameplay and earning in Song of Rising are many and varied, so don't hesitate to explore this guide further to learn more about the options available to you! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
