The multiplier option is in the errata, the last bit. it still looks quite a heavy handed correction to me. Nothing irreparable, but it is clear in the fluff text that Virgil is on par with the (legendary) founders of the OoH, or more. The problem is when the book does not differentiate between the items that could be created by a 1220 Augustan and the ones that could only be created by Virgil. That messes the section on items a lot. I find it strange that such a major feature was not included in the book and explicitly stated in the description of each item in the Animo section.
But well, I am sure that Jordi is already breaking the system to have a score of ninja stone golems created to fight in total darkness and commanding a host of flying daggers using Base 1 guidelines, so no biggie. He will probably give them a turtle shell, paint them green and train them to have brawl, weapon and cooking skills. Or something. Been there, seen him do that before. He is the one that challenged Pan Caudarax the dragon to a fire-breathing competition and won, after all.
