"So that's how it is...
"This is the constraint of the 'Promotion Fortress' on magic, huh...
"It's truly hard to believe; I actually only realized the existence of these 'constraints' now..."
Noland Lee muttered to himself.
Excited, ecstatic, and in awe, various emotions surged in his chest. Suddenly catching a glimpse of the truth behind the workings of magic, Noland found himself unable to suppress his trembling.
He now knew how to identify whether a spell was constrained by the 'Promotion Fortress'!
There were two specific criteria!
First, check whether the spell's 'Tier' was clearly marked on the Magic Panel.
'Death Two Finger', a high-level spell.
'Fear Spell', a common spell.
'Breath of the Dead', a common spell.
'Lightning Strike Technique', 'Lightning Spear Technique', common spells.
'Elemental Energy Summoning Technique', a common spell.
But!
'Elemental Reactor Summoning', 'Tier' unknown!
