Sigil: City of Doors

Where can you buy the recipe? They're not available in the RoN warehouse.

I think I saw a recipe for it in the laboratory, might remember wrong though?

Should be laboratory.

Yeah it's in the Laboratory in the Lower Ward. Saw it there today (alongside Brain Golem :) )

Actually brain golem should be buyable at the illithid hive. oh well. perhaps theres no shop.

Thanks, guys :)
