| ||For the item in Fallout 2, see Magic 8-ball.|
It has a weight of 1 and increases the Luck stat by 1 point (up to a maximum of 10) as long as it is carried in one's inventory. If it is dropped (including storing it in a locker in a house) a dialogue box will mention "no longer feeling lucky," and the Luck bonus will be removed until it is picked up again.
Unlike normal pool balls, it cannot be used as Rock-It Launcher ammunition.
- Unlike most items that boost stats, the Lucky 8 ball is considered a permanent increase, akin to a rank of Intense Training, not a temporary increase. This can cause issues;
- The effect counts for perk requirements, such as Better Criticals, which requires 6 Luck.
- The effect is not shown in the "Status Effects" section of the Pip-Boy, but the increased stat can be seen in the "S.P.E.C.I.A.L." section.
- If Almost Perfect (which raises all Special points to 9) is taken with the lucky 8 ball in the inventory, it will have no use. When dropped, it will actually LOWER Luck to 8, since it counts it as a semi-permanent increase. To get around this: upon hearing the drum roll for hitting level 30 (or before it happens), quickly open the inventory and drop the 8 ball. This will lower Luck by one, and allow getting 9 across the board without the ball. Picking up the 8 ball will raise Luck to 10. This means one can actually pick up the Luck Bobblehead long before level 30, just don't forget to drop the ball before taking Almost Perfect.
- Though it no longer serves any purpose, this item can be found in the game files for Fallout: New Vegas.
