A skill tree is a visual representation of a character's abilities and upgrades in a video game or role-playing game. It resembles a branching tree, with each branch representing a different ability or upgrade that can be unlocked as the player progresses through the game. The trunk of the tree represents the core skills that are available from the start, while the branches represent more specialized abilities that become available as the character gains experience points and levels up.
The skill tree allows players to customize their characters by choosing which abilities they want to focus on, and it encourages strategic gameplay by rewarding players who make thoughtful decisions about how to allocate their points. The structure of a skill tree can vary depending on the game, but generally speaking, it is designed to incentivize exploration and experimentation while also providing guidance for the player's progression through the game.
