Dezeroth's Eyes of Instruction

You stop the target for a moment, imbuing them with the ability to store and share memories on how they achieved a task. For the duration of the spell, they can opt to experiment with various activities, purposefully failing their ability checks. In exchange, they may still roll a d20 and instead record the result. They can replace any ability check made by an ally within 10 feet with this instruction roll. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. Only one d20 may be saved at any time.
