Ainz - God eye scroll

He dithered for a while, and eventually, he successfully emptied his mind, activating the spell at the cost of the scroll. Thought led only to doubt.

The spell used was God Eye.

A ninth-level spell, it generated an invisible incorporeal magic eyeball. He had not used this since the lizardmen incident.

The main differences between it and remote viewing through a magical item were increased range and the fact that it could simply pass through ordinary walls.

It was an excellent spell for reconnaissance, but not a flawless one. It was merely invisible and could easily be spotted with tier-two detection spells. And while incorporeal, if it did take damage, the feedback would harm the caster. Since it was classified as intelligence magic, anti-intelligence measures could reveal the caster’s location, and if he tripped an attack wall, there was a chance spells would come flying his way. But the greatest flaw was that the eyeball itself had no HP and borrowed neither level nor defense from Ainz himself.

The elf sentries worked in teams of three, armed with bows, but they did not see the God Eye sailing toward them.

Seems like they don’t have any way of seeing the invisible. But I can’t be sure other elves don’t have a class allowing it.
