Mystery Box
Back in his room, Lith used Invigoration on one of the few boxes he had left, carefully studying its pseudo cores, mana pathways, and the mana crystals that sealed it.
He had taken notes on everything he learned so far about them, and thanks to Soluspedia he could remember everything with but a thought.
He started simultaneously attacking the mana pathways and the mana crystals, letting the energy they contained leak at the same rate. While both were draining, Lith also had to prevent the three pseudo cores desynchronizing.
The last time he attempted opening the boxes, he failed because he had never wielded a crystal embedded item. Therefore he didn't know that the only way to prevent the prevent destructive desynchronization was to imitate the mana signature of the crystals and inject mana in the pseudo cores every time they would go out of phase.
