Dezeroth's Calculating Eyes

This spell utilizes a concept known as Antidivination, which posits that it's impossible to know, at the smallest level, the exact state of anything. By reducing, enhancing, or manipulating this phenomena, it's possible to utilize Divination spells in new and interesting ways.

You produce a temporary arcane intelligence, feeding it all the information of the environment that you're aware of. Next, you seal it away for ten minutes to calculate and unseal it. Finally, you absorb the calculations it's made thus far and sort through the simulated reality it's constructed thus far before trying again until the duration of the spell is over.

For the duration of the spell, you may explore the dungeon for an hour before returning to the point in time that the spell was originally cast. However, as you explore areas where information is less plentiful, the simulation becomes less reliable. At any time, you may be asked to make a DC15 Intelligence check. If you succeed, the information is reliable; if you fail, the simulation has failed and any detail may be altered.

As this spell operates off of the principles of Antidivination, a notoriously sensitive phenomena, it must be sealed away for ten minutes between simulated attempts.

At higher levels: When you cast this spell using a 5th level spell slot or higher, the duration of the spell is one hour longer per spell slot. However, the simulation itself remains to be for one hour.
