PREREQUISITE

TREE INVESTMENT
Lv.2 needs 2 Skill Points already spent in Witchcraft · Lv.3 needs 4 Skill Points already spent in Witchcraft. The target skill’s own cost does not count toward this requirement.

Is Aether Flow Worth Taking?
- Needs a prerequisite
- You have to learn Forbidden Sigils first.
- Opens a path
- 1 later skill 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 Aether Flow 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.
