For a fake mage, the trick to perform a Blade Tier spell was to perceive the tiny specks of mana that left their body to feed their equipment and follow them to locate the power core.
Blade Tier spells followed the same principles as tier five spells and once conjured, one could pour as much mana as they wanted. In Orion's case, he had to draw the energy from the power cores and add it to Elemental Sonata while keeping the spell matrix intact.
It was both slower and more difficult than what an Awakened would do since they would add the power from their equipment while weaving the spell instead of splitting the process into multiple steps.
On top of that, due to the lack of Spirit Magic Orion's Elemental Sonata used only six of the seven elements. The silver lightning became one with the Blade Spell and the multi-colored light of his blade turned white.
