Gotchas & Restrictions
- Tradeskill must be open — Most
C_TradeSkillUI functions only work when the tradeskill window is open. - CraftRecipe requires hardware event — Crafting requires a user-initiated action (click/key).
- Recipe schematic vs recipe info —
GetRecipeSchematic() provides reagent slots and quality data; GetRecipeInfo() provides name/icon/difficulty. - Crafting orders are async —
GetCrafterOrders() is async. Wait for CRAFTINGORDERS_CRAFTER_ORDER_LIST_UPDATED. - Quality tiers — Dragonflight+ recipes have quality tiers (1-5). Use
GetRecipeQualityItemIDs() to get items per tier. - Recraft — Recrafting uses
RecraftRecipe() with the item's GUID, not CraftRecipe(). - Profession specs use C_Traits — Under the hood, profession specializations use the same
C_Traits system as class talents with a different config type. - GetProfessions returns indices — Pass the index to
GetProfessionInfo(), not a profession ID.
