# Crates Like Treasure Chests, airdropped Crates come in three classes: Common, Epic, and Rare. Crate classification is based upon the types and quantities of items enclosed. There are three types of assets players can discover within Crates: Elements, Resources, and NFTs. Elements and Resources play similar roles in the HEALM ecosystem, as they will both be necessary for building on Planet Kepler-186f and on user-developed Planets. In the early stages of HEALM, users are encouraged to collect and save these assets as they will provide important utility from the launch of Planet Kepler-186f onward. --- # 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.
