That depends. Once you've finalized your build you're going to get souls like crazy, so that even if you fully upgrade a flame from scratch you won't even notice that you used some souls. Also Chaos Eaters drop the slabs very rarely.

Then again, you're guaranteed one slab per playthrough, and I can't really figure out why you'd want more than one (unless you want to have a +10 fire and +5 chaos for the trophies)
