Pathfinder Damage Dice Steps
I am building a Human Gunslinger character who uses the Racial Heritage feat to get access to the Goblin Gunslinger feat so he can use a large double hack-but without penalty. Problem is, the the table for converting the damage for weapons sized for medium creatures to damage for weapons sized for large creatures stops at 2d10 and the medium double hack-but does 2d12. What damage would a large double hack-but do?
Fair warning (as well as for anyone looking to reuse the concept), your GM might veto the idea because it doesn't fit RAW or thematically. Goblin Gunslinger allows you to use **Medium** firearm weapons with no penalty and its unlikely training with small creatures would help you use Large weapons because they still wouldn't be able to.
Size Changes, Effective Size Changes, and Damage Dice Progression: I'm confused by how to increase and decrease manufactured and natural weapon damage dice when the weapon's size or effective size changes. There's a bunch of different charts, and I'm not sure which to use.
When the damage dealt by a creature’s weapons or natural attacks changes due to a change in its size (or the size of its weapon), use the following rules to determine the new damage.
- If the size increases by one step, look up the original damage on the chart and increase the damage by two steps. If the initial size is Small or lower (or is treated as Small or lower) or the initial damage is 1d6 or less, instead increase the damage by one step.
- If the size decreases by one step, look up the original damage on the chart and decrease the damage by two steps. If the initial size is Medium or lower (or is treated as Medium or lower) or the initial damage is 1d8 or less, instead decrease the damage by one step.
- If the exact number of original dice is not found on this chart, apply the following before adjusting the damage dice. If the damage is a number of d6, find the next lowest number of d6 on the chart and use that number of d8 as the original damage value (for example, 10d6 would instead be treated as 8d8). If the damage is a number of d8, find the next highest number of d8 on the chart and use that number of d6 as the original damage value (for example, 5d8 would instead be treated as 6d6). Once you have the new damage value, adjust by the number of steps noted above.
- If the die type is not referenced on this chart, apply the following rules before adjusting the damage dice. 2d4 counts as 1d8 on the chart, 3d4 counts as 2d6 on the chart, and so on for higher numbers of d4. 1d12 counts as 2d6 on the chart, and so on for higher numbers of d12.
- Finally, 2d10 increases to 4d8 and decreases to 2d8, regardless of the initial size, and so on for higher numbers of d10.

I'd just like to point out that the Small versions of the chainsaw and butchering axe contradict the FAQ on this point.
@SuperJedi224 I just looked at both weapons and fail to see an issue with the chart. Could you explain what the issue is? Take the chainsaw, its 3d6 when medium and goes to 1d12 (which the chart would concert to 2d6). Thats two steps lower, which is both because medium and higher than 1d8. Same applies to the axe.
"If the initial size is Medium or lower (or is treated as Medium or lower) or the initial damage is 1d8 or less, instead decrease the damage by one step." Technically, this means a Small butchering axe should be 2d8.
