Dungannon said:I voted for option 3. As per our previous discussion, I think it depends on the specific PrC being created, and the idea behind it.
Chalk up a "mee, too".
Besides, indirectly at least, some PrC's FROM SQUARE ONE, have had attribute requiremetns.
Able to cast 3d-level spells? That's a roundabout Attribute requirement (an attribute of the right sort, at 13+) -- and the Loremaster requires that.
Feat with an attribute requirement? Well, if you require the feat, you require the attribute. Cleave requires a Strength of 13+, so the Blackguard (which requires you to have Cleave), already requires you to have a Strength of 13 or more.
Those two are right form the DMG PrC's, so attribute requirements for PrC entry has been around form the very beginning -- wether clearly stated or not.
So ... as said above: it depends entirely on the prestige class in question. Shoudl it ever be the SOLE entry requirement?
Well, of course not.
Can an additional requirement, specifically of a particular attribute (either a minimum OR a maximum), be a viable option? Of course!!
Do most Prestige Classes already require various specific attribute minimums, if only by way of spelclasting and feat prerequisites? Absolutely!!!
