"This is the Spear that once cut through dimensions to arrive in Antarctica, the very one used to finally slay the Great Elder of the Elder Race... Even if your consciousness realm can somehow contend with Mythical Level power,
but your body is too far removed from a Mythical structure.
Even if you could enhance it through some bizarre means, at best you could only achieve 'Ancestor Return'... The sheer hardness alone is of no use.
These defenses imbued with Divine nature, under my Eye, are also completely useless."
The Eye that Eugenes is currently using is something even Green desires immensely... It played a crucial role when he slayed the Golden Saint.
Such an Eye, belonging to the Shoggoth tribe, is the most perfect.
Be it in terms of completeness, precision, purity, or quality, it is far superior, and as an accompanying organ of the Shoggoths, it can evolve and perfect itself along with his growth.
'Locking' is but one of the abilities of this Eye.
