ArkinventoryRules_Profession is an additional rule for Arkinventory.
Use profession("[name of the profession]") to make the rule only apply to a character that knows that specific profession.
Works for all professions. The capitals in the search are ignored, so you can use capitals when you want to.
You need the following addon:
profession("engineering") and type("tradeskill") and subtype("engineering")
When the character knows the profession engineering, all engineering tradeskills will be shown.
This works for Retail, Classic and Burning Crusade Classic.
I removed the compatibility notice for the Classic versions, because the mod would not show up in the CurseForge App and when installed the app noted it as belonging to Classic.
