What is the difference between Ability Damage and penalty to an ability?

[Staffan]

To respond to the above: Penalties of all forms stack. So, you could hit someone with two Rays of Enfeeblement. Note, however, that the spell cannot reduce a target's effective Strength score to less than 1.

Actually, doubling up on ray of enfeeblement would fall under the rule that says "Spells that provide bonuses or penalties on attack rolls, damage rolls, saving throws, and other attributes usually do not stack with themselves."

So sure, you could hit someone twice with ray of enfeeblement. The result would be that he'd take the worse penalty, not both (and to a minimum of 1).

Right.

Another applicable quote:

"Same Effect More than Once in Different Strengths: In cases when two or more identical spells are operating in the same area or on the same target, but at different strengths, only the best one applies."

Wow that quote sounds like it might be applied to the Arcane Strike stacking question.
