[Smash Bros. SP] Should I clear the adventure “Star of Light”? Rewards and benefits for 100% achievement

Single user mode “Star of Light”.
Many people may have given up on the way because the map was too large.
In response to the question “Is there anything good about clearing this?”, we will honestly tell you about the clearing benefits and the meaning of doing it.

Clear bonus: Menu BGM change function

When you reach the true ending (defeating Keira & Darz), you will unlock the function that allows you to freely change the BGM on the menu screen.
This is the best reward for those who are tired of the default songs or those who want to play famous songs from past works.

Value as a spirit collector

It doesn’t really matter to the opponent, but you will get a large amount of powerful “Legend-class Spirits” in the process of clearing it.
These are useful for raising Amiibo and fighting against spirits in a special room.

Summary

If you are only interested in battles, it is OK to skip. If you want the ability to change the BGM, you can quickly finish the game on the “Easy” difficulty level.
