The capacity for spellcasting and utilizing certain skills is directly tied to a resource pool. Managing and expanding this resource pool is essential for sustaining ability usage in combat and exploration. Effective character builds often prioritize increasing the maximum value of this resource, allowing for more frequent and potent application of abilities.
A larger pool of this resource offers several advantages. It allows for longer periods of sustained combat without needing to pause to regenerate. It also permits the use of more costly abilities without quickly depleting available reserves. Historically, focusing on resource management has been a key aspect of character optimization in action role-playing games, leading to more efficient and powerful builds.
