I have been picking up bobbleheads and dumping them in my stash and not sure if I should be using them due to rarity. Is it worth just using them when needed or is there any reason to hold on to them? Also, if I do use one how long do the effects last?
There is really no point in saving them and you should use them when the time is right for a specific stat boost.
Bobbleheads respawn at lots of locations around the map and can be picked up again.
The effects last an hour so they can give a really good stat boost during a play session depending on what you want to boost.
Bobbleheads can boost the following:
Increase Heavy Guns damage by 20% for an hour
Improved caps stashes
+2 Charisma for 1 hour
Increase damage with Energy Weapons by 20% for an hour
+2 Endurance for 1 hour
Increase damage with Explosives by 30% longer for an hour
+2 Intelligence for 1 hour
5% more experience for 1 hour.
Increases Lockpicking Sweet Spot by 30% for an hour
+2 Luck for 1 hour
+20% Melee Damage for 1 hour
+2 perception for 1 hour
Fusion Cores last 30% longer for an hour
+2 Strength for 1 hour
1 extra hacking guess for an hour
30% harder to detect for an hour
