Lockpick (Fallout 3)

Lockpick is a skill $$ Its functionality was replaced by the Locksmith perk in Fallout 4 and the Picklock perk $$

This skill determines the difficulty of locks the player is able to pick.

Initial level

 * $$\text{Initial level}=2+(2\times\text{Perception})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Perception of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=14.5$$

Description
In Fallout 3, the Lockpick skill determines which locks one can attempt to pick. The skill must be at least the lock rating to try, and locks are rated at increments: Very Easy - 15%, Easy - 25%, Average - 50%, Hard - 75%, and Very Hard - 100%. With the prerequisite skill, picking a lock takes the form of a mini-game.

Investing in this skill also increases the probability of successfully forcing the lock open, which, combined with the Infiltrator perk, can be a convenience mechanism. The chance of forcing the lock can be found by taking their skill, subtracting the requirement for the lock, and adding 10%.
 * Example: Skill of 67 - Average lock (50) + 10 = 27% chance.
