Trained Memory (3.5e Feat)
From D&D Wiki
Trained Memory [General]
You have the incredible memory of a preliterate scholar.
Prerequisite: Int 15+, at least 8 total ranks in Knowledge skill(s).
Benefit: As a full-round action, you may retry a Knowledge skill check. The first retry on a question requires a full-round action. Each subsequent retry takes 10 times as long as the previous one.
If you roll a natural 1 (the d20 comes up 1) on a Knowledge retry, you cannot retry further on that question until you increase your ranks in that Knowledge skill.
Normal: You may not retry Knowledge skill checks.
