# Campaign
### Rule
* Unlocked from the start of the game.
* The campaign consists of multiple chapters, each chapter containing a certain number of nodes.
* To proceed to a new node, the previous node must be completed, and to proceed to a new chapter, all nodes of the previous chapter must be completed.
* There is no limit to the number of times a node can be attacked until it is cleared. However, players will consume stamina for each attack.
* A node is considered fully cleared when the player achieves **3 stars** in that level. The conditions for achieving each star will be specified for each level, mainly completing the level, preventing any enemies from entering the main base, etc.
* Upon clearing a node, players will receive rewards, which consist of **2 types**:
**First-time Reward** is the reward received when the conditions for obtaining stars are met (only received once per node).
**Farmable Reward** is mainly a small amount of gold, experience, players can replay nodes to earn more of these resources
* To unlock other features of the game, it is based on campaign progression.
### Node Design
* Each node will have its own unique map, including enemy positions, the main base, and different paths.
* Each node will have the following specified parameters: **Initial cost** (to deploy heroes), **Number of enemies**, **Main base health** (for each enemy, except the boss, that enters the main base, the health will be reduced by **1**, when the health is depleted, it is considered a loss).
* The number of heroes allowed to be carried is **10 for each level**, but the maximum number of heroes that can be deployed at the same time in a battle is **8**. There will be special levels where the number of heroes that can be carried and deployed will change, but mostly it is **10 and 8**.
* The difficulty of each level will gradually increase, mainly by increasing enemy strength, adding enemies with special skills, adding paths for enemies, etc.
* At the end of each chapter, a boss will appear, and when the boss enters the main base, all the health of the main base will be deducted.
