3.5 Unarmed Strike 2d10 Goes to What?

[Diarmuid]

Say you had a 20th level monk (for whatever reason) dealing base 2d10 damage. What would their damage progression be if they took Improved Natural Attack, had Enlarge Person cast on them, or Greater Mighty Wallop...or some combination of all three?

4d8 for the next step (increase to large size)

[Diarmuid]

Just noticed that Large Monk section myself. And 4d8 has a progression on the weapon size chart up to 6d8 from there. Looking at the rest of the chart, is it safe to assume that further increases would just keep adding 2d8?

[LTwerewolf]

Large would be 4d8, Huge would be 6d8, Gargantuan would be 8d8, and Colossal would be 8d10 from what I'd extrapolate. It would probably stop there.

Thing its, if I remember correctly, the Monk's unarmed progression doesn't match the normal weapon damage one.

It doesn't for the unarmed progression, but monks don't progress their unarmed strike after 20, even into epic levels, so it's then all based off size increases, which are the same for any weapon or natural attack.

The size increase tables in the books go up to 12d8, IIRC, so before then there really isn't anything to ask about.

In general, the tables work if you increase via individual dice instead of overall. So 2d10 becomes 1d10+1d10 becomes 2d8+2d8 becomes 4d8, while 4d8, as 2d8+2d8, becomes 3d8+3d8=6d8. The table obeys this all the way up to 12d8, and past that you can extrapolate: 16d8, 24d8, etc. Note that you need an actual size for the weapon to effectively occupy, so you can't go past Colossal.
