Swift Learner

Swift Learner is a Fallout, Fallout 2, Fallout Tactics, Fallout 3 and Lionheart Perk.
 * Requirements: Level 3 (2 in Fallout 3 and Lionheart), IN 4
 * Ranks: 3
 * Benefit: You are indeed a Swift Learner with this Perk, as each level will give you an additional +5% (Fallout, Fallout 2, Fallout Tactics) or +10% (Fallout 3) bonus whenever you earn experience points.
 * Notes: Best purchased at an early level. Help you gain levels faster, but you'll end up "losing" perks in the long run (except in Fallout 3). In the current Fallout 3 you should really consider skipping this perk unless you're in a real hurry to gain experience, the maximum player level (20) is not high enough to make it worthwhile in the longer run. When the level cap is raised in Broken Steel it may be worthwhile, considering you will need 66,700 experience points to reach level 30, making it more than twice the experience needed to gain the first 20 levels.
 * Note: The condition Well Rested will give you the same effect as one level of Swift Learner for 12 hours. With all levels of Swift Learner this allows for a bonus of 40% to all experience points you gain.
 * Bug: Does nothing in Fallout Tactics.
 * Bug: In Fallout 3, even when you have 3 ranks in this perk, it will still show up in your level-up perk list to choose. If you choose it, you will not end up with 4 ranks, instead you'll find you still have 3 ranks and have simply wasted a perk.  Unsure if this bug affects other multi-rank perks.
