I have been looking around for the standard stat boosters and skill boosters and still haven't seen anything that will boost my S.P.E.C.I.A.L. I was wondering if there are any things hidden away like the bobble heads in 3 that I might be missing.
From the collectible standpoint, there are 7 Snowglobes. However, these don't give you stats. Instead they can be sold for caps. A whole heck of a lot of caps.
To increase your SPECIAL stats, there are Implants available for purchase, that will increase any stat by +1, as well as Implants to grant health regeneration and increased DT. You can purchase a maximum number of Implants equal to your Endurance score.
To increase skills permanently, there's only books - 4 for each skill except for Repair, for which there are only 3. With the Comprehension perk, each book gives 4 points in it's associated skill, for a maximum of 16 points from books - 12 for Repair.
