Your mind opens to the secrets of the cosmos and briefly touches the omniscience of the gods.

You gain a +5 insight bonus on all Knowledge checks.

At any point before the duration expires, you can make a check with a Knowledge skill in which you have no ranks, or retry a Knowledge check you have previously failed.

The +5 insight bonus still applies in both of those cases, but utilizing this option reduces the spell's remaining duration to 1 minute/level.

If you worship a deity who grants access to the Knowledge domain, the bonus is +10 rather than +5--even if you did not choose that domain.
