The "Pandoric Illusion Formation" was a rather infamous formation, according to the "Beginner's Formation Compendium" at least. Although it was a rather simple formation, it was one of the most formidable illusion formations in existence.
The formation casts multiple different illusions onto one person, and those illusions, due to the formation's instructions, fight and absorb each other for supremacy. The result? One super-powered illusion that is extremely difficult to neutralize.
'But, it's expensive...' Alaric sighed.
In Alaric's hand, on top of the formation, was a set of 6 low-tier soul shards. These would allow the formation to last about 15 minutes. He brought these with him, with Sonic's help, from Ooze Village.
After all, he expected to need them to practice formations.
