Gotchas & Restrictions

• Transmog NPC required — C_Transmogrify.ApplyAllPending() and related functions only work at a transmog NPC.

• sourceID vs appearanceID — A sourceID is a specific item drop source. An appearanceID is the visual look (multiple sources can share one appearance).

• Category by armor type — Transmog categories are divided by armor slot and armor type (cloth, leather, mail, plate).

• Dye system is new — The dye color system is new in 12.0.0 and APIs may evolve.

• Barber shop requires presence — C_BarberShop functions only work while at the barber shop NPC.

• Outfit limit — There's a maximum number of saved outfits per character.

• Set variants — A base set can have multiple variants (different difficulties, etc.). Use GetVariantSets() .

• illusion = weapon enchant visual — Illusions are the weapon glow effects. Separate from armor transmog.
