Defines a node within the skill tree, including its unlock cost, prerequisites, and refund behavior. Each node can have verify actions (conditions to check before release), consume actions (costs to pay), and prerequisite nodes that must be released first. When a node is restrained (reverted to unreleased), the consumed resources are partially refunded based on the restrain return rate. The return acquire actions are automatically calculated from the consume actions multiplied by the restrain return rate.

Metadata
Arbitrary values can be set in the metadata. Since they do not affect GS2’s behavior, they can be used to store information used in the game.
List of verify actions executed before releasing this node to check whether the conditions are satisfied. For example, can verify that the player has a certain level or possesses a specific item. If any verify action fails, the node release is rejected. Maximum 10 actions.
List of consume actions executed when releasing this node, representing the cost to unlock it. These actions are also used to calculate the return acquire actions: each consume action is reverted at the restrain return rate when the node is restrained. At least 1 consume action is required. Maximum 10 actions.
List of acquire actions executed when restraining (reverting) this node, representing the resources returned to the player. This field is auto-generated from the release consume actions multiplied by the restrain return rate. For example, if release costs 100 gold and the return rate is 0.8, restraining returns 80 gold. Maximum 10 actions.
restrainReturnRate

Restrain Return Rate
The rate at which consumed resources are refunded when this node is restrained (reverted to unreleased state). A value of 1.0 means full refund, 0.5 means half refund, and 0.0 means no refund. Defaults to 1.0 (full refund). Valid range: 0.0 to 1.0.
premiseNodeNames

List of Premise Node Names
Names of other node models that must be released before this node can be unlocked. Defines the dependency graph of the skill tree. A node cannot be released unless all its prerequisite nodes are already released. Maximum 10 prerequisite nodes.
