Simulate a non-existant Ability score

[Dark_Ansem]

we already know how the PRC team simulates a lack of constitution score (undead): a + 12 to said constitution.

Constitution
     Any living creature has at least 1 point of Constitution. A creature with no Constitution has no body or no metabolism. It is immune to any effect that requires a Fortitude save unless the effect works on objects or is harmless. The creature is also immune to ability damage, ability drain, and energy drain, and automatically fails Constitution checks. A creature with no Constitution cannot tire and thus can run indefinitely without tiring (unless the creature’s description says it cannot run).

how would you simulate lack of other abilities in an engine like NWN?

Strength
Any creature that can physically manipulate other objects has at least 1 point of Strength. A creature with no Strength score can’t exert force, usually because it has no physical body or because it doesn’t move. The creature automatically fails Strength checks. If the creature can attack, it applies its Dexterity modifier to its base attack bonus instead of a Strength modifier.

Dexterity
Any creature that can move has at least 1 point of Dexterity. A creature with no Dexterity score can’t move. If it can perform actions (such as casting spells), it applies its Intelligence modifier to initiative checks instead of a Dexterity modifier. The creature automatically fails Reflex saves and Dexterity checks.


Intelligence
Any creature that can think, learn, or remember has at least 1 point of Intelligence. A creature with no Intelligence score is mindless, an automaton operating on simple instincts or programmed instructions. It has immunity to mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects) and automatically fails Intelligence checks.

Mindless creatures do not gain feats or skills, although they may have bonus feats or racial skill bonuses.

Wisdom
Any creature that can perceive its environment in any fashion has at least 1 point of Wisdom. Anything with no Wisdom score is an object, not a creature. Anything without a Wisdom score also has no Charisma score.

Charisma
Any creature capable of telling the difference between itself and things that are not itself has at least 1 point of Charisma. Anything with no Charisma score is an object, not a creature. Anything without a Charisma score also has no Wisdom score.

no idea? I know the rules say to treat a non-existing ability like a +0, but honestly that would imbalance the game a lot if applied literally (all those creatures with a 10 in those vacant stats...)

Does a 0 ability score equal a -5 on skill checks or an autofail on skill checks related to that ability?

[Dark_Ansem]

I think it only equals a -5, is not an autofail.
