From my own experience, I think I can safely guess he's referring to equipment. If you're making a character above, say, 6th level, and you want him to not be totally irrelevant in any situation involving the dice, you need to go through and spend thousands or millions of gp, keeping a close eye on the bottom line and bonus-to-cost ratio at all times. The higher level you go, the more important items become, and the greater percentage of your gear is custom-made.Not sure what you mean?
However, with your rules, it's just four artifacts that fit the character, and a few non-Epic stuff to shore up the weak points a bit. Simple, and much more fun.
