Initial level

Example: A starting Intelligence of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$$

Description
Science primarily allows for hacking of terminals using a mini-game. Certain terminals have different difficulty levels, and different Science skill levels are required to hack them. The difficulty ratings and skill levels are: Very Easy (15), Easy (25), Average (50), Hard (75), and Very Hard (100). The difficulty of the mini-game is relative to the player character's Science skill. Harder terminals have more words, longer words, and fewer brackets.
