General heroes can be upgraded by collecting the same hero cards, and NFT heroes need hero coins which can be purchased with Pocket Stone(PKS).\ \ Hero, that can grow up to 10 levels, will play a key role in the battles with its strength, attack power, armor, and unique active and passive skills ## Soldier Collection / Level-up Players can upgrade the level of soldiers by merging two of the same level and type soldier cards, and can randomly get one higher-grade soldier card by merging three soldier cards of the same grade, regardless of their type. If you want to survive a ruthless battle, you must have strong soldiers. ## Formation Players can strategically deploy their own heroes/soldiers before the battle. Grasp the attributes and skills of heroes and soldiers well. Even if the same squad battles each other, the results may vary depending on the formation. Build your own formation to beat the enemy and get higher winning rates! --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://meversedex.gitbook.io/pocketbattlesnftwar/pocket-battles/game-system/formation-level-up.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
