AD&D Rules Interpretation & Clarification

D.G. 8/93, 1/97

Ability Scores:

For Most Races:
Roll three sets of 4d6 in ability order, taking the three high numbers, and add a 1 if the fourth die is a 1.
Abilities: Strength, Constitution, Dexterity, Alertness, Intelligence, Wisdom, Charisma, Comeliness
If an ability comes up a 19, it will be an 18 plus a roll of a d00 + 10%. This allows an ability to exceed 18, though rarely.
Ability scores are improved through training, aging, magic, or using NWP Options.
Training during or between adventures adds 1d30 to % of any ability studied per level or quarter year of study.
Aging is usually detrimental to physical, but augments intellectual traits.
NWP Options: Two abilities per class can be improved on as follows (1 per level):
Magic Users: Int, Dex
Priest: Wis, Cha
Fighter: Str, Con
Thief: Dex, Alt
Psi/Monk: Wis, Con
Multiclass: All of each class
These (2) abilities begin with a d00% and are by "spending" a Non-Weapon Proficiency (which adds 3d20). Once 101% is reached, ability score bumps up to next number.
