# Decorations When the Training Tanks reach a certain level, it is possible to add Decorations to them. These are very special, limited NFT pieces, which certainly maximize the appearance of the Tanks. Decorations fit into one of the decoration slots that the Training Tank has available. We can place, remove and exchange Decorations at will. Being NFT pieces, we can also sell them to other players. --- # 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.
