Is there a formula for scaling damage dice that does NOT increase the number of dice rolled, but instead increases the size of the dice rolled? For example: At 2nd level you roll 1d4; at 5th, 1d6; at 9th, 1d8; at 13th, 1d10; at 18th, 1d12 (dice caps at a d12) I get... close but I can't seem to work up the exact formula needed
