Age of Ashes creature Stat Block incorrect?

[KainPen]

Are a lot of these Stat Blocks incorrect for creatures? I am trying to program Chapter 2 in to a virtual table top and I am coding it in. I notice some creatures are getting extra damage from no where. Like a Charau-ka butcher in a sense has striking rune for debris throwing ability. But it is not mention any where, or why it does more the base Charau-ka with the same ability. There is also just random +3 damage past str mod score on all damage of that creature. I know, it supposed to be little more free form with monster creation with pathfinder 2nd edition. It make sense with natural attacks for creature, but when they are using the same equipment as PC, that equipment should function the same. There is also and Alchemist built like a pc stat block that is getting bonus damage +3 on all it's weapons, even Crossbow that not supposed to get that kind of bonus damage. It make me wonder if it is a mistake. The consistence of the +3 extra damage on creatures status block in the chapter, make me think it someone accidentally had their calculator add 3 to the stat blocks.

That's as intended for PF2.

Monster design uses different rules from PC building, which are found in the Gamemastery Guide.

The design philosophy for those monster design rules is also different from Pathfinder 1st edition. It's no longer a pick out the pieces and add them all together process, but a pick the end-result because that's what actually matters process.

I will point out the monster in question is actually slightly overstated, as it was intended to be a level 8 creature but was shifted to a level 6 later.

The +20 it has is beyond extreme hit bonus for a level 6, but only a high hit bonus for a level 8. To rectify this, simply lowering the hit bonus to +17 (high for a level 6) works, although you can run them as written (I did, party was lucky not to wipe at the mine).

Age of Ashes has some wobbly statblocks as it was developed parallel to monster creation rules but yeah, you don't build them like you did in PF1 where monsters and NPC ran on the same math as PCs.

I was wondering, I knew it was supposed to be free form, but I thought it would be bit more less wobbly, then what it is in this AP. I think as you pointed it was written at the same time the monster creation rules where being developed. This is more then likely why the are like this. I would have not noticed if I had not been programming this stuff, in a computer. Made me question balance of monsters a bit and if it was a mistake. I bet it as Exocist said of the creature was designed to be higher level then it is listed as and changed. Thus it has extra damage and higher bonus to hit was not adjusted. I will make my own adjustments. I think even thou they are not built the same. I think certain pieces should still function the same such as weapons. Especial if there is not a listed reason as to why. Alchemist creature mention above has ability stating that it can use magic staffs, could not the same been done for using, cross bow and doing extra damage. After programming the Alchemist further the extra damage was not included on staff attack that is on all it's other weapons. If extra damage is going to be added to things and not giving a reason, I think it should be a bit more consistence and be added to all the weapons. Hopeful there will be less wobbly stat-blocks in future release now that they have a standard method of creature creation now. Thanks for all the info
