Blowguns and Damage Die Steps

[Tekrala]

So Inventor adds a couple of options to weapons that allow damage die increases for any simple or martial weapon (2 increases for simple weapons.) With that in mind, I wanted to ask the community, what do you think this does to the blowgun's damage?
In 1e, I would just say to make the damage a d2 but both d2s and d3s aren't really used in 2e so I'm left confused about how to approach this. It doesn't help that the rules about die steps in the CRB starts at d4s and doesn't go any lower. Thoughts?

Blowguns should probably be d4s. In 1e unnarmed was a d3 and got bumped to d4 so it will probably be that or 1 damage with added effects instead.

From the other thread on this:

Increasing Die Size [Core Rulebook pg. 279]

"When an effect calls on you to increase the size of your weapon damage dice, instead of using its normal weapon damage dice, use the next larger die, as listed below (so if you were using a d4, you’d use a d6, and so on). If you are already using a d12, the size is already at its maximum. You can’t increase your weapon damage die size more than once.
1d4 ➞ 1d6 ➞ 1d8 ➞ 1d10 ➞ 1d12"

looks like 1d4 is the minimum and 1d12 is the maximum of the list. Since 1 isn't on the list, it looks like you can't increase it.

I had the same thought.

Disappointingly, i think Graystone is right, that seems consistent with the way they're ruling and errata-ing things in pf2.

Since it's outside the bounds of the provided rules, it simply doesn't apply.
