✅Sapling & Tree NFT Gameplay Integration

In TimberLegends, Saplings and Trees are more than just collectibles—they form the foundation of the game’s resource economy. Saplings produce TIMBER passively over time, acting as the entry-level production units. By blending Saplings with a specific NFT and TIMBER, players can evolve them into Trees, which offer significantly higher TIMBER output and other in-game features. This system introduces a progressive gameplay loop that rewards player engagement and strategic planning, while also creating demand for both base and upgraded NFTs within the ecosystem.
