Pls help, I think the our DM is in trouble Vs 100 simulacrums
our DM is a new DM we are all relatively new players, I used to DM for before, anyways the DM created something called a " Mana Geyser" it's a magical item that allows the user to limit the magical levels of the world in a specific place like stopping teleport rings and circles from working and every spell higher than lvl 2 automatically fails or actually has no effect, this " Mana Geyser " collects the magic from the area and gives it to it's user allowing them and who ever they choose to use magic freely in the area with limited magic for others, iam not sure if he intend for it to be only for enemies and not something we use as players, at some point we managed to distract the user and his allies to move away from it we were in a cave and the other party members ran in different tunnels to move them away from it , I managed to get to it trying to disable it ( iam a artificer and the other party members are a warlock, sorcerer and a monk) the DM tells me I can't and it only interacts with wizards and sorcerer ( after I got a high result with the arcana roll for it something like 23 or more I don't remember now ) when our sorcerer came trying to stop it the DM revealed it can boost the users lvl and allows them to be lvl 20 temporarily ( we were lvl8) now this lvl 20 sorcerer used a wish spell to wish for a simulacrum of his lvl20 self and told that simulacrum to also wish for one until he got 10 lvl20 sorcerer simulacrums .
After a while one of the enemies managed to use dispel magic on 9 of them, the remaining one was in a different place that simulacrum used it's wish like before until there were 100 simulacrums , the sorcerer gave everyone 5 simulacrum , and after some fights we got to lvl 10 , now my question how do we fix this and how do I help my DM fix this without stepping on the sorcerer shoes or the DM's
Update: Thank you all for your input and great advice, I sent some comments from this post to the DM and researched some points with him, we just finished our session , the DM at some point in talking with the sorcerer told him he will eventually kill them all ( the simulacrums) with another magic field or he would upset a very specialised guild that Hunts ppl's clones because of some fear of clones. the sorcerer also tried to say he can sacrifice sorcery points to get that lvl eazly, at the end I had to inter the chat and explain to both the mistakes in calculation and told the DM not to deduct the lvl we got and told the sorcerer he gets to keep one simulacrum both said ok , but the DM informed us he made one of the enemies survive after we killed him, Again thank you for the help
