I want costume production on some SH24/SH25 building.
It should produce costume without hero for reasonable cost (1 4* ascension mat for 5* costume, 1 3* unfarmable ascension mat for 4* costume and 1 3* farmable ascension mat for 3* costume for example) along with millions of iron. Costume should be random of requested rarity.
Time of production should be something like 3d.
Or maybe do not consume unfarmable mats, but just use millions of iron and farmable 3* mats for TC20-like odds for costumes only.
