I don't really need a mask but I'll create one (not that I will ever use it.)

Name: Arcana

Magic:

Superpower Magic

Transcendent Magic

Ethereal Magic

Chaos Magic

I changed it to masks.

Ok. Edited my comment.

◇ Mask Name ◇

[The] Verb

◇ Magic Arsenal ◇

☆ Ethereal Magic

☆ Transcendent Magic

☆ Yin & Yang Magic

The Double

Endless Magic

Fictional Magic

Quantum Magic

Utopian Magic

So let's say I place the mask on and suddenly I get a download. I experience the lives of four different alternate-universe versions of myself (my doubles, as the mask is called), each one of whom has studied a different form of magic for twenty-five years.

After the download is complete, the mask crumbles away to dust, leaving me imbued with the above powers and the knowledge required to use them. I'm also a hundred mental years older.
