D&D 3E/3.5 Mixing 3.0 and 3.5

[Allensh]

I own the core books for both 3.0 and 3.5. I own all of the class splatbooks for 3.0 and none of the 3.5 supplements at all other than Lords of Darkness. I am considering embarking on a campaign using the original Adventure Path that Wizards published. Are there major issues involved in mixing 3.0 and 3.5? Will this cause me problems at some point, aside from having to rename some skills and the like?

I don't think it is an issue at all. I've been combining 3.0 and 3.5 for a long time now. I've never had any problems doing this.

Converting Damage Reduction has always been a pain for me. I have heard of a conversion chart somewhere, but have been unable to locate it.

As for Oriental Adventures in 3.5, just remember the update to the relationship between Monk unarmed attack progression and BAB. Other than that there shouldn't be any problems.

Either way...just my 2 cp

The Conversion booklet can help. It's not a chart, but a set of guidelines. http://www.wizards.com/default.asp?x=dnd/dnd/20030718a

It shouldn't be a problem. I ran an adventure path using 3.0 rules with the 3.5 versions of classes and the complete books (sort of the inverse of your situation) and it worked well. I was able to eyeball the little stuff as it came along. I did spend extra prep time on most of the big encounters, tweaking differences in monsters mostly. Like hanniball said, DR was something to watch out for.

I don't even think that you need converting DR. Just keep whatever DR a creature has. If it's 3.0 style like 20/+3 then you still need a +3 weapon to bypass it; if it's 3.5 style like 5/magic and cold iron, you need a +1 cold iron.

Not even skills are a problem. If a character has a 3.0 skill that was merged with another, he still has it as a separate (just make DC lower for a more specialized skill). So if someone has Read Lips and Spot at the same time, she could use both to actually read lips, but because the Read Lips is more specialized it should be easier to succeed. There's nothing in the rules that says all skills must be completely separate.
