Potential Skill Nodes with Options

In this kind of nodes, you can decide which Potential Skill
to learn among several options.

As for each optional Potential Skill in that node, the required
materials are the same, but the number of levels to be raised
may be different.

You can tap on the node again to "forget" the learned
Potential Skill.

After you forget the learned Potential Skill, that node will be
restored to its default.

To forget a learned Skill, you must consume Dragon Stones
or an identical character.

The Potential Skill nodes with options are marked with a star.
