Tag! (Fallout 3)

Tag! is a perk

Effects
Because of the reduced properties of tag skills, this is essentially nothing more than a fifteen point bonus to any given skill.

While tagged skills do not have the same benefit as in previous games, this perk is the highest skill bonus perk in the game, along with the perk Size Matters, as all others are +10 (not including Impartial Mediation, as it requires neutral karma and therefore is not always active). It is useful for quickly bringing a new skill up to the level of the starting skills, e.g. 60 Lockpick becomes 75, enough for a hard lock, and then the skill points can be added to make it 90.
