Skill Rate/Fallout 2

Skill Rate is a derived statistic

Gameplay

 * $$\text{Initial level}=(\text{IN}\times2)+5$$

The amount of skill points received on each level up is primarily dependent on one's Intelligence. Every level of experience will give the player character skill points. It can be further modified by certain traits or perks, such as the Skilled and Gifted traits, as well as the Educated perk.

One can also tag three skills. Tag skills are skills one can specialize in. Each tag skill gains +20% and increases twice as fast. With the Tag! perk, one gains an additional Tag skill.
