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. 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. If the level cap is raised in future updates of the game, it might be something to consider for levels 21-23.
 * Bug: Does nothing in Fallout Tactics.
