Pathfinder 2e Roll20 Fall of Plaguestone Question (P2 Rules)

Hi, This is not a bug report.  The module is fine. I am not new to gaming, but I am trying to learn Pathfinder 2 after playing a lot of P1 and other games. The big bad guy of part 1 of The Fall of Plaguestone is Hallod. Hallod's damage with both kukri and fist is dice +6.  Hallod's strength is a +4 modifier and I am trying to understand where the +6 came from.  Does anyone know?  He seems to have +2 damage more than I can account for. Thanks, Dan 

NPCs aren't always constructed 100% by-the-book rules when it comes to their stats, so it can be a conscious choice to increase the damage done while still using the same damage dice for the variability of the damage.

Hey Andreas, Thanks for the reply.  That's how I am looking at it, too.  The NPC is supposed to be a brute, so I can easily rationalize the extra damage. Dan
