Any player character with an Intelligence of 25 or above can, once per session, gain the benefits of the hypercognition power.

Any player character with a Wisdom of 25 or above can, once per session, manifest the effect of path of the exalted (BoED spell, the effects of which are reproduced below for convenience).

(A PC with both Int and Wis of 25+ can do one of those things in a session, but not both.)

Path of the Exalted

Path of the exalted allows the caster to consult her deity (or an agent of her deity) to help make a difficult decision. This decision is usually more complex than a simple morality question. It may involve strategizing, choosing a particular lead to follow in an investigation, deciding who to help, or other difficult choices.

The deity or agent simply helps the character examine a known situation from a number of different angles and makes a recommendation about the correct path to take. This spell does not reveal unknown factors, but merely helps the caster analyze known elements. The spell ends when the deity or agent has provided sufficient guidance for the caster to arrive at a decision.
