Is Endless Effort Worth Taking?
- Opens a path
- 2 later skills sit behind it, so spending here also unlocks what comes next.
- Manual-gated
- Skill Points alone are not enough: levels above the free ones also need Endless Effort Manual.
These are the gates and follow-ups the game data confirms, not a ranking. Which skill is worth it depends on the build you are already running.
