How to change merchant tables in crucible

is there any way to change the merchants in crucible mode to have specific static items? i’ve extracted the arz files for survivalmode1 and 2 and i can’t even find the merchant (kandral) in the creatures/npcs folder

Extract also survivalmode (without digits). Merchant is default NPC available in vanilla crucible.

found it! thank you. do you know if there’s a way to add static items though? rather than just the tables it accesses

As i know it possible but couldn’t say right now how exactly it works.
