This one is a little bit more difficult to guess. If they stick with DnD rules, you can' just add in additional damage on creatures or additional resistance. They *may* have to fine tune each encounter to figure out the appropriate number of adds and at what CR they would have to be. I'd say less than 40% but this is a guess
