If you're trying to level up the Strongest Sorcerer (yes, the Gojo clone!) to his upgraded unmasked form, you're going to need Six Eyes—a pretty rare and essential item in Anime Last Stand.
What is Six Eyes?
Six Eyes is a high-class evolution material used to reveal the complete potential of the Strongest Sorcerer unit. After evolution, the unit became incredibly powerful with upgraded abilities and graphics, and that made it a favourite among fans for end-game material.
In order to get your hands on Six Eyes, you will need to play Challenges. You can find these inside a cave in the main lobby area. If you happen to have trouble looking for it, you will locate a sign that reads "Challenges," or, more conveniently, use the TP toggle on the left half of your screen to be brought to the realm of challenges instantly.
How do you obtain it, and why is it needed?
Challenges are timed modes that repeat periodically, and the Six Eyes item has a chance to drop upon completing specific stages of the challenges. All runs do not necessarily drop one, so prepare to grind several times. Use your strongest units and possibly group up with friends or utilise public lobbies so as to clear stages more efficiently.
To evolve Strongest Sorcerer into his unmasked form (basically Gojo Satoru’s peak form), you’ll need:
2x Six Eyes
6x Common Spirit Shards
25x Spirit Shards
The base Strongest Sorcerer unit
