I am well aware of the fact that ability scores are open-ended. I was referring to ability score enhancement, i.e an Enhancement bonus to ability scores.
In the 3.0 DMG (page 176) it said: "Most items that add to ability scores are restricted to a maximum bonus of +6, and the bonus usually comes in multiples of 2 (+2, +4, +6)."
I always read that to mean enhancement bonus to ablity scores was limited to +6, and interperted the "most" as referring to the Inherent bonus which specifically said "A character is limited to a total inherent bonus of +5 to any ability score".
The matching section in the 3.5 DMG is missing the paragraph in which the above limitation on ability score enhancement is stated. I can find no place where this limitation is mentioned (although it's possible I missed it).
It therefore appears that in 3.5, as opposed to 3.0, there is no limit to ability score enhancement.
Is that right?!!!
P.S, the Epic Level Handbook provided rules to exceed mortal limitations such as +6 to ability scores or +5 on swords, I know. I am refering strictly to non-Epic rules.
