Not sure if anyone else does this, but I like to max out on cdr and get rylais. Since Q can count as a single-target spell, you have the potential to permaslow a target. Max cdr makes this a lot more manageable. I personally choose to do this because I don't think Karthus' E is worth using in most circumstances. Its damage isn't impressive, it has a short range, and putting it to good use is often suicidal. I think his damage is most impressive when he can land consecutive Q's, and it's easier to do this with rylais and cdr.
