Character Ability Scores are what determine a character's mental and physical attributes. All character ability scores can be increased permanently by tomes, enchanted items while they are equipped, or temporarily using potions and spells.
Character ability score table (Baldur's Gate and Tales of the Sword Coast)Edit
Hit Point adjustment: A number that is added to or subtracted from the gain of hit-points when the character reaches a new level. The number in parentheses is only for Fighters, Paladins, Rangers and Barbarians (the four warrior classes and their sub-classes). The Constitution bonus to HP is only applied for the first 9 levels for warriors and for the first 10 levels for rogues, priests and wizards. If a character's constitution score is raised, hit points for previous levels are added retroactively.
Resurrection Survival: The percentage chance that a character is Resurrected or Raised successfully from the dead by magic. Characters whose bodies were too damaged (or "chunked" by a heavy blow) when they were killed cannot be raised.
Regeneration: At 20+ constitution scores, characters start regaining lost hit-points automatically.
"Shorty Saving Throw Bonus": Gnomes, Dwarves and Halflings receive a bonus to all saving throws, depending on their score. This bonus is between 0-5.
Bonus spells: The number of additional spell slots the priest receives for a Wisdom score, which are cumulative. A priest with a Wisdom of 19 receives +3 level 1 spell slots, +2 level 2 spell slots, +1 level 3 spell slots and +2 level 4 spell slots.
Spell failure (%): The chance that an attempt to cast a spell fails. Wisdom determines this for all classes and spell types.
Lore Bonus: See Intelligence. This bonus is cumulative with Intelligence.
Reaction adjustment: How an NPC reacts. The computer generates a random number between 8 and 12, then adds or subtracts bonuses or penalties from the character's Reputation and Charisma. Negative reactions may mean a quest isn't offered, and positive reactions may lead to a better quest reward, for example. Charisma is another factor which has an influence on the prices in shops.
