The first letter of the abbreviation is used to help group and quickly identify the type of the skill. The number following the abbreviation in the prerequistes column is the minimum skill needed to acquire the skill.
As per the manual, it is necessary to advance all linked skills to at least one level higher than the desired level for advancement. More plainly, to advance heavy shields to level 3, it is necessary that both light and medium shields are at least level 3 as well.
I'm also including in this list the left-out skills in the list in case that Heuristic Park implements them. At the moment, Repair, Identify, Scout, Steal, and Alchemy aren't implemented.
I've moved the scout skill to the general group instead of the thief skills where most of the text places it since skill analysis makes the grouping seem illogical. At the same time, I've left backstab with the thieving skills even though the game displays it as a diabolic skill.
