Lockpick (Fallout: New Vegas)

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
Lockpick in Fallout: New Vegas operates in much the same way as Fallout 3, with the Lockpick skill determining which locks the game will allow the lockpicker to attempt picking. Their skill must, again, be at least the lock rating to try, and locks are rated at 25% increments: Very Easy - 0%, Easy - 25%, Average - 50%, Hard - 75% and Very Hard - 100%. With the prerequisite skill, picking a lock takes the form of a mini game (see Lock for details).
