The highlight of the strong Astral group was the coordinated fighting: combining twelve into one, spreading one into twelve.
When the Twelve Stars worked together, the Star Switching Astral Formation unleashed so many extraordinary powers.
But when the Twelve Stars were not together, each member of the Astral was just one mage with no superior power than a normal mage.
The only advantage that the Astral members had was that they had the magical items created by Merlin. Although they were not as invincible as a Spiritual; Weapon, the things that were made by a Green-level Alphabet User were definitely not ordinary.
Three years had passed; Merlin devoted most of his time to using the alphabet powers to produce magic potions, invent alphabet crystals, and create various magic items. It was unseeable by how much Merlin's concentration power had increased.
Possibly, Merlin's properties at the moment could have even reached the zone of the Violet-level Alphabet User.
